Conclusions
-
1.
It is established that the level of carbide and nitride phase dissolution in chromium-manganese steels of type Kh16G18 with a varible ratio of carbon and nitrogen in them reaches a maximum at 1150°C. With an almost identical lattice spacing the degree of its distortion in steel with nitrogen is greater and therefore the specific electrical resistivity of the steel is higher.
-
2.
The degree of strain hardening for austenitic steel type Kh16G18 containing carbon and nitrogen depends on the relationship between these elements, and as a rule it is greater, the higher the nitrogen content, which is connected with the higher structural defect density and formation of ε-martensite in steel with nitrogen.
-
3.
In chromium-manganese steel type Kh16G18 with the maximum nitrogen content (0.45%) after cold plastic deformation with εtru = 1.2 a higher level of strengthening was achieved with retention of its nonmagnetic nature than for steel with 0.45% C.
