摘要
Abstract
The effect of different heat treatment processes on microstructure and mechanical property of X80 bend pipe was studied. By the comparison of two different heat treatment processes, the effect of heat treatment for the microstructure and mechanical property of X80 parent material and weld was discussed. The result showed that the microstructure and mechanical property of X80 bend pipe was seriously affected by the heat process. By the heat process of 950°C quench+500℃ tempering, the microstructure of heat-affected zone(HAZ) and girth weld had been refined. Furthermore, the toughness and the micro-hardness of the pipe steel and the girth weld had been improved, which indicated that the heat process of 950℃ quench + 500℃ tempering is suitable for the production of X80 bend pipe.关键词
