分类号 TG454Technology of Merging Brazing and Heat-Treating into One in Vacuum for Martensitic Stainless SteelLiu Hong Li Wen Zhang Shihang(Shenyang Institute of Technology,Shenyang 110015) [Abstract] The technology of merging brazing and heat treating into one in vacuum for martensitic stainless steel is investigated
Not only the joint's strength and remelting temperature are tested, but also the joint's metalloscopy and fractograph are observed
The results show that the joint is compact and the quality is good
[Key words] martensitic stainless steel,vacuum brazing,heat treating
