Some observations of voids formation were carried out by using low carbon steel with three kinds of heat-treatment, namely, normalizing, annealing and spheroidizing.
对三种不同热处理(正火、退火、球化)的低碳钢中微空洞的形成进行了一些观测。

The most commonly used heat treatments on metals are softening annealing, quenching, normalizing, surface hardening treatment, precipitation hardening.
最常见的热处理包括软化退火、淬火、正火、表面强硬化、淀积硬化。

The properties of the dies can be improved through pre treatment-high tempreature annealing or normalizing.
