HARDNESS OF NITRIDED LAYERS TREATED BY PLASMA NITRIDING

Acta Polytechnica CTU Proceedings, 2020
Stainless steels, particularly the austenitic stainless grades are widely used in many industries due to good corrosion resistance, but very poor mechanical properties as surface hardness and wear resistance limit its possible use.

Microstructure and mechanical properties of austenitic stainless steels manipulated by trace TiC–TiB2 nanoparticles

Journal of Materials Research and Technology
It is difficult to simultaneously increase strength and toughness of austenitic stainless steels through traditional heat treatment and alloying. However, adding nano-sized ceramic particles is a potential method to manipulate the microstructure and ...

Predicting the Ms temperature of lean alloyed ferritic–austenitic stainless steels

Journal of Materials Research and Technology
A set of laboratory hot-rolled and thermally cycled 19–22 wt% Cr lean alloyed ferritic–austenitic stainless steels were studied with respect to calculated equilibrium austenite composition and experimental martensite start (Ms) temperature.
