钙含量对h.1模具钢冲击功的影响机理

冲击功是评价h.1模具钢服役性能的重要特征之一。针对国内某钢厂生产的h.1模具钢出现冲击功波动较大的现象,结合微观组织分析、夹杂物表征及对比分析和热力学理论计算,探究了导致h.1具钢冲击功波动的主要原因和Ca对Mgo·Al_(2)o_(3)夹杂物的转变机理。研究结果表明,大尺寸的d.类夹杂物是导致h.1模具钢冲击功较低且波动较大的主要因素(试验钢室温无缺口冲击吸收功平均值由(327±3.4)j降低至(233±26.1)j),确定了钢中的Ca含量是导致d.d.类夹杂物超标的主要原因。结合商业热力学软件Factsage 8.2计算结果可知,当试验钢中Ca质量分数较低(h.1模具钢中夹杂物以高熔点Mgo·Al_(2)o_(3)类夹杂物为主,此类夹杂物不容易聚合长大;但当试验钢中Ca质量分数较高(0.0009%)时,由于Ca对Mgo·Al_(2)o_(3)夹杂物的改性作用导致钢中夹杂物以容易聚合长大的低熔点Cao-Mgo-Al_(2)o_(3)类夹杂物为主,但是此类夹杂物很难从钢液中去除,导致了h.1模具钢中d.类夹杂物超标。同时发现,在冲击载荷作用下,大尺寸夹杂物(>10μm)会首先从基体中脱粘并引起微裂纹,微孔周围内应力的局部集中导致了裂纹萌生和裂纹扩展,进而降低了试验钢的冲击吸收功。最后,提出通过优化冶炼工艺过程降低Ca含量是解决h.1模具钢中大尺寸夹杂物超标问题的主要攻关方向。
