Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Incoloy A-286 is a Fe-Ni based superalloy and it is widely used in gas turbine industry, jet engines and other applications. Although A-286 has a long service history, the fabrication of A-286 is not without any challenges. The hot deformation property for this alloy is highly sensitive to its composition, especially the content of impurity such as sulfur (S). In present study, a batch of A-286 has suffered from cracking issue during rolling process at high temperature and detailed examinations have revealed that phenomena of liquation of Ti-rich phase induced by eutectic reaction with S appeared at grain boundary and caused intergranular fracture. To improve the hot deformation behaviors of A-286, alloy design has been performed with the minor addition of magnesium (Mg). Furthermore, its combined effect with manganese (Mn) has been examined. Experiments include tensile tests at 1050oC and 1175oC, cyclic oxidation at 900oC, detailed microstructure/fracture surfaces observations and composition analysis by OM, SEM-EDS, TEM-EDS, Auger, and EPMA. In conclusion, Mg addition can eliminate the phenomena of Ti-rich phase liquation, the high temperature deformation behaviours of A-286 can then be improved.
