出于满足各种性能要求的动机以及经济原因，多材料零件已被更多地了解并频繁地用于各种工业应用中。1）镍基高温合金在各种工业（例如化学、石油化工、航空航天和核电站等。2 -4）在各种镍基高温合金中，在石化、发电和核工业中使用的部件的制造中对超级合金C-276的需求是巨大的。5，6）这是由于存在Cr、Mo和Fe作为主要合金元素，它们有助于在高温应用中的高强度以及高耐腐蚀性。2，7，8）由于超级合金C-276的价格高，用价格相对较低的材料替代它们在经济上是可行的。稳定级321奥氏体不锈钢（ASS）最近已被用作蒸汽气体重整器中的管材，并且是在较低风险条件下替代超合金C-276的绝佳选择。9，10）因此，因此，有必要研究C-276高温合金异种焊接接头以及脉冲钨极氩弧焊工艺对镍基高温合金/C-276异种焊接接头的影响。奥氏体不锈钢
Multi-material parts have been more acquainted and frequently used in various industrial applications with a motive to meet various property requirements as well as for economical reasons.1) Nickel-based superalloys plays an important role in the development of various industries such as chemical, petrochemical, aerospace and nuclear power plant etc. due to high corrosion resistance and high strength.2–4) Among the various nickel-based superalloys, the demand for Superalloy C-276 in the manufacturing of components used in petrochemical, power generation and nuclear industries are enormous.5,6) This is due to the presence of Cr, Mo and Fe as major alloying elements which contribute to high strength as well as high corrosion resistance at elevated temperature applications.2,7,8) Owing to the high price of Superalloy C-276, it is economically viable to substitute them with a comparatively low priced material. Stabilized grade 321 austenitic stainless steel (ASS) has been recently employed as a tubing material in steam gas reformers and would be an excellent choice to replace Superalloy C-276 under lower risk conditions.9,10) Therefore, it is necessary to investigate the dissimilar joint of Superalloy C-276 and Effect of Pulsed Current Gas Tungsten Arc Process on the Dissimilar Weldments between Nickel-based Superalloy/ Austenitic Stainless Steel
