Abstract |

内容記述 |
The transforming process was traced on 1%Cr-0.5%Mo steel in the conditions of as-hot-rolled, quenched-and-tempered. The rapid heating process was employed from the viewpoint of weld thermal cycle. In as-hot-rolled specimen, austenite grain nucleates at ferrite/pearlite boundary, and grows into massive from. In quenched and quenched-and-tempered specimens, two types of austenite grains were observed. One nucleates at prior-austenite grain boundary, and grows into massive form as same as hot-rolled specimen. Another one nucleates at the inside of prior-austenite grain along the lath structure of martensite. The starting and finishing temperatures of transformation rises with increasing heating rate. The rise of temperature is larger for as-hot-rolled specimen than for quenched specimen. The size of austenite grain decreases with increasing heating rate, however, the condition of specimen before transformation does not effect the final size at the end of transformation. The segregation of phosphorus was discussed on the basis of the moving speed of transforming interface, which was determined by the experiments. |
