摘    要:通过热力学计算及实验,研究了含钛汽车用非调质钢在液态和凝固过程中含钛夹杂物的析出规律.研究表明,通过调整非调质钢中O,Al和Ti的含量,可以控制夹杂的形态和尺寸,从而得到细小、弥散非金属夹杂物作为针状铁素体的形核核心,细化钢的组织,提高钢的强度和韧性.

关 键 词:非调质钢  夹杂物  晶内铁素体  钛氧化物  非调质钢  钛氧化物  冶金行为  steel  oxides  titanium  强度  钢的组织  形核核心  针状铁素体  非金属夹杂物  尺寸  形态  控制  含量  调整  析出规律  凝固过程  液态  汽车用

Abstract:The precipitation behavior of inclusions containing Ti in liquid steel and during solidification of a Ti-bearing non-quenched and tempered steel was investigated by experiment and thermodynamic calculation. The results showed that the size and morphology of inclusions in the non-quenched and tempered steel could be controlled by adjusting the contents of O, Al and Ti, and fine and disperse non-metallic inclusions might be obtained as the nuclei for intra-granular ferrite, which could refine grains and improve the strength and toughness of the steel.
Keywords:non-quenched and tempered steel  inclusions  intra-granular ferrite  titanium oxides
