求翻译：退火是将钢加热到适当温度,保温一定时间,然后缓慢冷却的热处理工艺,它的目的是降低温度,提高塑性,改善切削加工性能,消除钢中的内应力,细化晶体均匀组织,为以后的热处理做好准备,其常用的退火方法有扩散退火.等温退火等温退火球化退火去应力退火和再结晶退火等是什么意思？

Annealed steel is heated to a suitable temperature, holding a certain time, then slowly cooling the heat treatment process, its purpose is to reduce temperature, increase plasticity and improve the cutting performance, eliminate internal stress in steel, refined crystal uniform organization for the
