14Cr-0.5Mo不锈钢脆性原因分析
|
摘要
本文对低冲击功14Cr-0.5Mo不锈钢进行分析。结果表明,网状碳化物的形成是影响14Cr-0.5Mo不锈钢冲击韧性的主要原因;终锻温度过高和冷却速度过慢是网状碳化物形成的一个重要因素。提出用高温扩散热处理可以改变网状碳化物的分布,并且证明了用这种方法消除网状碳化物是可行的。
The 14 Cr-0. 5 Mo stainless steel with low impact energy is analyzed in this paper. The results show that the formation of network carbide is the main reason affecting the impact toughness of 14 Cr-0. 5 Mo stainless steel. Excess final foring temperature and too slow cooling rate during the forging process are important factors for the formation of network carbide. It is suggested that the distribution of network carbide can be changed by heat treatment process with high temperature diffusion,and it is proved that the network carbide eliminated by this process is feasible.
