Structure of steels after high-speed plastic deformation
- 20 Downloads
The formation of interlayers with high-temperature structures depends on the composition of the steel and its structural condition. In steels 60, 18Kh2N4MA, and 17GSND the interlayers consist of martensite, and in steel 12Kh21N5T of ferrite.
The interlayers are formed in local zones during deformation at high rates where considerable heating occurs — ∼1250° in steel 12Kh21N5T, for example.
