1. Martensitic-austenitic steels of the type N19M2T2B possess high strength and plasticity (530–560 HV, σu=1760–1900 N/mm2, δ=8–10%, ψ=40–50%, and a1=50–60 J/cm2), high fatigue strength, thermal-cycling stability, resistance to erosion u

When sintered iron with a certain porosity (14–20%) is saturated with nitrogen, the amount of absorbed N2 and the depth of the nitride layer increase jumpwise. If we regard the porous material as a biphase mixture (of pores and iron particles), suc

Hardening heat treatment of a number of promising martensitic-austenitic steels [i, 2] predetermines presence in the structure of different amounts of martensite, equilibrium quench austenite, and phase-hardened (forming during aging as a result of ~

The K1c criterion can be used efficiently to evaluate the mechanical properties of the silicide layers; we determined the conditions of local brittle fracture and showed the applicability of the method of determining K1c on the basis of the length of

1. Nitriding of steel N21M2TB in the biphase α+γ condition produces a nonbrittle nitride case strongly adherent to the base metal. 2. The main reason for the acceleration of the nitriding process and the lack of brittleness is dispersed particles o
