Steel with an ultimate tensile strength of 2500MPa, a hardness at 600–670HV and
toughness in excess of 30–40MPam1/2 is the result of exciting new developments with …

The average use of AHSS in car body design has increased significantly over the past 20
years. This growth is not only an average mass growth, but the variety of available grades …

A model is developed to describe the endpoint of carbon partitioning between quenched
martensite and retained austenite, in the absence of carbide formation. The model assumes …

A novel concept for the heat treatment of martensite, different to customary quenching and
tempering, is described. This involves quenching to below the martensite-start temperature …

Three heat-treatment routes incorporating bainite formation, namely bainite-based
quenching plus tempering, bainite austempering and bainite-based quenching plus …

Bainite has been obtained by heat treatment at temperatures as low as 125° C in a high
carbon, high silicon steel. This has had the effect of greatly refining the microstructure, which …

This paper presents a detailed characterization of the microstructural development of a new
quenching and partitioning (Q&P) steel. Q&P treatments, starting from full austenitization …

In recent years there has been an increased emphasis on the development of new
advanced high strength sheet steels (AHSS), particularly for automotive applications driven …

An alloy system based on iron is described in which it has been possible to create a high
density of interfaces by heat treatment alone. The resulting structure consists of a mixture of …

A fine-scale bainitic microstructure with high strength and high toughness has been
achieved by transforming austenite at 200° C. X-ray diffraction analysis showed the carbon …
