摘　　要：通过了解奥氏体不锈钢的化学特性和力学性能,来分析其金相组织的生成和分布。使用不同的材料,采用不同的焊接方法,在薄板奥氏体不锈钢焊接接头的母材、熔合区和焊缝的金相图中,寻找金相组织的构成情况,组织的生长方向、晶粒尺寸的变化情况,从而为超声波检测提供方向。Analyze the formation and distribution of metallographic structure of austenitic stainless steels by understanding their chemical properties and mechanical properties.Using different materials and different welding methods,in the metallographic diagram of the base metal,fusion zone and weld of the thin plate austenitic stainless steel welded joint,the composition of the metallographic structure,the growth direction of the tissue,and the change of grain size are sought,so as to provide direction for ultrasonic testing.

关 键 词：奥氏体不锈钢 晶粒尺寸 晶粒方向 金相组织
