Abstract :in this study, Inconel 738LC superalloy brazed by insert ignore into journalissuearticles values(28Ni72Ti); which was used as an active filler alloy at temperature  at  985ºC  for  insert ignore into journalissuearticles values(15min); this process achieved  in a furnace  brazing  under high purity of a protective gas insert ignore into journalissuearticles values(99.999 Argon gas);  to ensure   that  joints  free from  oxidation   and  contamination.   The XRD and   microstructure  analysis  was  implemented   to  investigate  the  bonding  morphology  and   the bonding strength was estimated from shear  test. The results illustration that highest shear strength was 29 MPa and  the morphologically  the  strength of  bonding  was  inclined by  the creation  of  reaction  layers that  cross over in the center of   the  brazing area  due to the  interdiffusion effects of  several constituents from base  metal insert ignore into journalissuearticles values(738 superalloy ); and active brazed metal insert ignore into journalissuearticles values(28Ni72Ti);. Use of word processing software It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor`s options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork. To avoid unnecessary errors you are strongly advised to use the `spell-check` and `grammar-check` functions of your word processor. Article structure General guidelines for online submission: Elsevier can accept text files in most standard word-processing formats but Microsoft Word is preferred. All online submissions must be accompanied by a covering letter detailing what you are submitting. Please indicate the author to whom correspondence should be addressed insert ignore into journalissuearticles values(in the case of multiple authors); and include a contact address, telephone/fax numbers for the corresponding author and e-mail addresses for all authors. Length of papers Published articles are normally less than 10 printed pages; this approximately equals a typewritten paper of 20 double-spaced pages plus a typical number of figures insert ignore into journalissuearticles values(8 or so);. Use double spacing and minimum 1-inch insert ignore into journalissuearticles values(3 cm); margins, and 12 pt font size standard fonts. Pagination Please ensure that your manuscript is paginated, as this will help both editors and reviewers to process it promptly. Subdivision - numbered sections Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 insert ignore into journalissuearticles values(then 1.1.1, 1.1.2, ...);, 1.2, etc. insert ignore into journalissuearticles values(the abstract is not included in section numbering);. Use this numbering also for internal cross-referencing: do not just refer to `the text`. Any subsection may be given a brief heading. Each heading should appear on its own separate line. As a general guideline, the preferred order for sections is: abstract, introduction, experimental, results, discussion, conclusion, acknowledgements, references, appendices. Introduction Provide a critical assessment of the literature relevant to the problem at hand, delineating unresolved issues. State clear objectives to explain how this study will take the field forward. Experimental Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described. Error bars: Error bars are required on all experimental and calculated data points with an explanation in the text as to how the errors were determined. SI Units SI units should be used throughout. Theory/calculation A Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis. Results Results should be clear and concise. Discussion Should develop cogent explanation for the results and explore their significance. In the case of computational studies, results should be compared with information available from published experimental work, if possible. Conclusions The main conclusions of the study may be presented in a short Conclusions section, which should stand alone. Appendices If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. insert ignore into journalissuearticles values(A.1);, Eq. insert ignore into journalissuearticles values(A.2);, etc.; in a subsequent appendix, Eq. insert ignore into journalissuearticles values(B.1); and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc. Essential title page information • Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations, acronyms and formulae where possible. • Author names and affiliations. Where the family name may be ambiguous insert ignore into journalissuearticles values(e.g., a double name);, please indicate this clearly. Present the authors` affiliation addresses insert ignore into journalissuearticles values(where the actual work was done); below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author`s name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author. Author names may not be added after a paper has been accepted. • Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that phone numbers insert ignore into journalissuearticles values(with country and area code); are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author. • Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a `Present address` insert ignore into journalissuearticles values(or `Permanent address`); may be indicated as a footnote to that author`s name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes. •It is not necessary to submit the title page as a separate document. However, if this option is chosen, please also include title page information at the beginning of the text document. Abstract An abstract is required for all papers. The abstract should indicate the content of the paper, and should describe the main conclusions. An effective abstract is brief and normally less than 250 words. Abstracts should not exceed 300 words. References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Graphical abstract Graphical abstracts are not accepted for this journal. Keywords Immediately following the Abstract, provide a maximum of 5 keywords which appropriately represent the contents of the paper. Abbreviations Define abbreviations and acronyms when they first appear in the article. Ensure consistency of abbreviations throughout the article. Acknowledgements Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research insert ignore into journalissuearticles values(e.g., providing language help, writing assistance or proof reading the article, etc.);. Math formulae Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus insert ignore into journalissuearticles values(/); instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text insert ignore into journalissuearticles values(if referred to explicitly in the text);. Artwork Electronic artwork General points • Make sure you use uniform lettering and sizing of your original artwork. • Embed the used fonts if the application provides that option. • Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar. • Number the illustrations according to their sequence in the text. • Use a logical naming convention for your artwork files. • Figures and captions to illustrations should be submitted on the same page. • Size the illustrations close to the desired dimensions of the published version. • Submit each illustration as a separate file. .
