The retained austenite transformation prior to the necking of the example enhanced the uniform elongation rate.
分析认为：残余奥氏体在颈缩发生前的较完全转变有利于提高均匀延伸率；
A more uniform strength of rupture and the rupture elongation of the fabric can be obtained in each direction.
织物各向的断裂强度和断裂伸长也比二向织物均匀。
The microhardness and tensile strength of stir zone increase compared with the base material, and the elongation increases significantly due to its fine and uniform microstructure of the specimen.
搅拌区细晶组织的显微硬度及抗拉强度相比于铸态母材有所提高，而伸长率显著提高。
