０Ｃｒ１６Ｎｉ２２Ｍｏ２Ｔｉ奥氏体钢在闪光焊接过程中，材料经快速加热到熔融温度并强烈变形，焊接熔合区内形成纳米晶组织，熔合线处纳米晶的尺寸为 ２０ ｎｍ，随距熔合线距离的增大纳米晶尺寸增大，纳米晶层的厚度为５０μｍ．此纳米晶形成的原因是半固态金属经强烈塑性变形使其中固相组织碎化及其引起的细化．
In the process of flash welding, the material is rapidly heated to the melting temperature and deformed strongly, and the nanocrystalline structure is formed in the welding fusion zone. The size of the nanocrystal at the fusion line is 20 nm. With the increase of the distance from the fusion line The size of the nanocrystal is increased, and the thickness of the nanocrystalline layer is 50 μm. The reason for the formation of this nanocrystal is due to the strong plastic deformation of semi-solid metal in which the solid-phase tissue is fragmented and its refinement is caused.
