合金元素在中的作用

钴能强化铁素体,加入碳素中,在退火或正火状态下能提高的硬度、屈服点抗拉强度,对伸长率断面收缩率有不利的影响,冲击韧性也随着钴含量的增加而降低。由于钴具有抗氧化性能,在耐热耐热合金中得到应用。钴基合金燃气涡轮中更显示了它特有的作用。(10)硅(Si)硅能溶于铁素体奥氏体中提高的硬度强度,其作用仅次于磷,较锰、镍、铬、钨、钼、钒等元素强。但含硅量超过3%时,将显著降低的塑性韧性。...

中各元素的作用

碳(C)中含碳量增加,屈服点抗拉强度升高,但塑性冲击性降低,当碳量0.23%超过时,的焊接性能变坏,因此用于焊接的低合金结构,含碳量一般不超过 0.20%。碳量高还会降低的耐大气腐蚀能力,在露天料场的高碳钢就易锈蚀;此外,碳能增加的冷脆性时效敏感性。铬(Cr)铬能增加的淬透性并有二次硬化的作用,可提高碳钢的硬度耐磨性而不使变脆。...

【材料课堂】热处理特辑—回火

回火后得到回火索氏体,指马氏体回火时形成的铁素体基体内分布着细小球状碳化物(包括渗碳体)的复相组织。力学性能:25~35HRC,较好的综合力学性能。应用范围:广泛用于各种较重要的受力结构件,如连杆、螺栓、齿轮及轴类零件等。工件淬火并高温回火的复合热处理工艺称为调质。调质不仅作最终热处理,也可作一些精密零件或感应淬火件预先热处理。45正火调质后性能比较见下表所示。...
