IMPROVEMENT OF MECHANICAL PROPERTIES OF STRUCTURAL STEELS BY MULTI-PHASE STRUCTURE FORMATION

The monograph is devoted to improving the mechanical and exploitation
characteristics of Advanced High Strength Steels through the development of the heat
treatment technology based on the “Quenching & Partitioning” (Q&P) principle. The
experimental data presented in the monograph clearly reveal the advantages of Q&P
technology over standard heat treatment technologies due to the formation of a multi-
phase structure with advanced properties. Special attention is paid to the retention of
austenite in the structure, its metastability to strain-induced martensite transformation,
and the contribution of the TRIP effect to the steel behaviour under the load. The
monograph is hoped to be of interest to researchers and engineers specializing in
metallurgy and heat treatment of metals.
