Effect of precipitates on the austenite grain growth of titanium microalloyed high performance steel

工程科学学报, 2016
An austenite grain growth model was established by analyzing the quantificational relationship between precipitates and austenite grain size. The austenite grain size of Ti microalloyed steel with the interaction of TiN and TiC panicles was calculated by

Effect of γ→α Phase Transformation on Refining Austenite Grains of Microalloyed Steel in Continuous Casting by Simulation

High Temperature Materials and Processes, 2016
The formation of coarse prior austenite grain is a key factor to promote transverse crack, and the transverse crack susceptibility can be reduced by refining the austenite grain size.

Control of Upstream Austenite Grain Coarsening during the Thin-Slab Cast Direct-Rolling (TSCDR) Process

Metals, 2019
Thin-slab cast direct-rolling (TSCDR) has become a major process for flat-rolled production. However, the elimination of slab reheating and limited number of thermomechanical deformation passes leave fewer opportunities for austenite grain refinement ...

Prior austenite orientation reconstruction of coherently transformed products and its application on austenite twinning

工程科学学报, 2018
High-angle grain boundaries and martensite/austenite (M/A) constituents are two critical factors that contribute to low impact toughness in metals. The generation mechanism of the high-angle grain boundaries is closely related to the crystallography of ...
