Abstract

Titanium nitride precipitation on a primary inclusion particle during solidification of bearing steel has been tracked by varying temperature in a confocal scanning violet laser microscope. Upon precipitation, an obvious growth of titanium nitride on a primary inclusion particle was observed due to the rapid solute diffusion in liquid steel. The onset of titanium nitride precipitation did not change with primary inclusion particle size, but the time of growth was greater for a smaller primary inclusion particle. Meanwhile, the particle size displayed little influence on the total precipitated amount of titanium nitride on it under the same conditions. At the later period of solidification, almost no change occurred in inclusion size, but the inclusion shape varied from circle to almost square in two-dimension, or cubic in three-dimension, to attain the equilibrium with steel.

轴承钢凝固过程中氮化钛在原生夹杂颗粒上的析出行为
用共聚焦扫描紫外激光显微镜观察了轴承钢凝固过程中初生夹杂颗粒上氮化钛的析出。析出后,由于钢液中溶质的快速扩散,氮化钛在初生夹杂颗粒上生长明显。氮化钛析出的开始时间不随初生包裹体粒径的变化而变化,但初生包裹体粒径越小,生长时间越长。同时,在相同条件下,晶粒尺寸对氮化钛析出总量的影响不大。在凝固后期,夹杂物的大小几乎没有变化,但夹杂物的形状在二维上由圆形变为接近方形,在三维上变为立方体,达到与钢的平衡。
