Special features of the structure of thick-walled forgings from steel 15Kh3NMFA
- 25 Downloads
The structural components formed in the transformation of austenite in steel 15Kh3NMFA in the ferrite-pearlite, bainite, and martensite regions are classified. The fine structure, the conditions of its formation, the behavior in tempering, and the effect on the mechanical properties of the steel are investigated.
