熔敷金属组织主要是针状铁素体,少量的先共析铁素体。
The microstructure is composed of acicular ferrite and a little proeutectoid ferrite.
结果表明,随冷却速率的增大,先共析铁素体的晶粒尺寸减小,体积分数增大,针状铁素体增多;
The results show that with the increase of cooling rate, the grain size of proeutectoid ferrite decreases, the volume fraction of proeutectoid ferrite and acicular ferrite increases.
