钢的回火脆性钢的回火脆性(与回火后钢的冷却条件有关的脆性),这一个题目,在解决制造业中使用不含钼钢材的问题上,特别迫切,一直到现在,很多研究还是说,没有一种无钼钢,不是倾向于形成回火脆性的。实际上,成品回火后,是快速冷却的话,无钼钢是保证能用的。可是有很多成品,要求具有最小的残余应力(旋转轴,透平机叶,挖掘机轴等等);而为了要制作这些成品,就必需寻求:没有回火脆性倾向 Temper brittleness of temper brittle steels (brittleness associated with the cooling conditions of tempered steel) after tempering of steels is particularly pressing in addressing the issue of using molybdenum-free steels in the manufacturing industry, and up until now, many The study goes on to say that none of the molybdenum-free steels did not tend to form temper brittleness. In fact, the finished product tempering, rapid cooling, then, without molybdenum steel is guaranteed to use. However, there are many finished products that require minimal residual stresses (rotating shafts, turbine blades, excavator shafts, etc.) and in order to make these finished products it is necessary to seek: no temper brittleness tendency
