Austenite Formation in a Cold-Rolled Semi-austenitic Stainless Steel

Metallurgical and Materials Transactions A, 2013
The progress of the martensite (a¢) to austenite (c) phase transformation has been thoroughly investigated at different temperatures during the continuous heating of a cold-rolled precipitation hardening metastable stainless steel at a heating rate of 0.1 K/s.

The Influence of Rapid Tempering on the Mechanical and Microstructural Characteristics of 51CrV4 Steel

Metals
The microstructure and mechanical properties of a low-alloy medium carbon steel (Fe-0.5C-0.9Mn-1Cr-0.16V, in wt.%) were investigated after rapid tempering and compared with a conventionally tempered counterpart.

Development of a Thermo-Metallurgical Model to Predict Heating and Austenitization of 22MnB5 for Hot Forming Die Quenching

, 2017
Hot forming die quenching (HFDQ) is used to transform ultrahigh strength steel blanks into martensitic body-in-white components that are lighter than parts made from traditional mild steels, without sacrificing crash performance.

A prediction model for austenite grain size distribution of casting slab in thermal rebound process: Considering α-ferrite precipitation and re-austenization

Journal of Materials Research and Technology
The precipitation and re-austenitization behavior of α-ferrite during thermal rebound process of casting slab are crucial to the austenite grain size distribution. Accurately obtaining austenite grain size distribution plays an important guiding role for

Anisotropic Transformation Strain and Its Consequences on Distortion during Austenitization

, 2012
The distribution of segregations, which is introduced in the continuous casting process and modified during succeeding manufacturing steps, is considered as an important "distortion potential carrier" for chemically banded steels. This article presents a
