Nanocrystallization of Bulk Steels through γ/α Transformation

Abstract:

Article Preview

A method of obtaining nanocrystallized bulk steels through phase transformation was investigated. Firstly, the austenite grain size of a microalloyed steel was refined to 1~3μm through repeatly heating and quenching; secondly, the samples with ultrafined austenite grains were heavily deformed at different temperature, and the uniform microstructures with some 0.1~0.3μm equiaxed ferrites were obtained.
