Effect of the type of stress on the mechanical properties and structure of martensite-aging stainless steel
- 18 Downloads
The resistance of Kh16N5D3 steel to plastic strain under a two-dimensional stress can be described, in the case of an isotropie body, when σ1 > σ2 by the Von Mises criterion and when σ1 < σ2 by the Saint-Venant criterion.
There is a linear relationship between the arbitrary yield point and the physical widening of x-ray interference fringes of martensite at various levels of strain hardening.
The type of stress affects the development of strain aging and has practically no effect (with the exception of n=0.5) on the uniform plasticity or on the microstructure of steel in the fracture zone.
