Over many decades, significant efforts have been made to improve the strength-elongation
product of advanced high strength steels (AHSSs) by creating tailored multi-phase …

This article presents an overview of the developments in stainless steels made since the
1990s. Some of the new applications that involve the use of stainless steel are also …

Additive manufacturing (AM) creates digitally designed parts by successive addition of
material. However, owing to intrinsic thermal cycling, metallic parts produced by AM almost …

There is sufficient experimental evidence to propose that the formation kinetics of athermal
martensite directly depends on the austenite grain structure from which the martensite forms …

A systems approach that integrates processing, structure, property, and performance
relations has been used in the conceptual design of multilevel-structured materials. For high …

New experimental evidence confirms the dependence of the martensite-start temperature on
the austenite grain size. The Fisher model for the geometrical partitioning of austenite grains …

Alloying traditionally enhances material properties by adding small amounts of secondary
elements to a primary base. Over the past decade and a half, a revolutionary strategy has …

It is demonstrated that in a high-carbon steel where carbide precipitation is suppressed,
bainite can be obtained by isothermal transformation at temperatures as low as 200 C. The …

Abstract A Quenching-Austenite Reversion Treatment (Q-ART) is used to process an Fe-0.2
C-8Mn-2Al (all in wt.%) medium Mn steel to investigate the effect of pre-existed austenite on …

Three stabilization mechanisms—the shortage of nuclei, the partitioning of alloying
elements, and the fine grain size—of the remaining metastable austenite in transformation …
