Meta-bainitic heat-treatment in steel

摘要

Bainitic transofrmatin process is divided into primary stage,in which meta-bainite without carbide is formed,and secondary stage,in which classical bainite is become.Meta-bainite is obtained with austempering in steel containing -Si or with air cooling after austenitizing in meta-bainitic steel.Meta-bainite possesses a good combination of mechanical properties.A lot of advantages appear in meta-bainitic steel.
