摘要
通过模拟焊接热影响区粗晶区组织,对模拟后的试样进行不同温度下的消除应力退火处理,测得其相应的冲击韧性,确定了P460NL1钢的再热脆化的温度区间,并通过对断口的分析,找出了产生再热脆化的原因,从而确定了最佳的消除应力退火温度。
By simulating the coarse - grained texture in welding heat affected zone, the test specimens after the simulation are annealed at different temperatures for disposal stress, the impact toughness is tested and the reheat embrittlement＇ s temperature range of the steel P460NL1 is learned. Then by the analysis of fracture face, the reasons for reheat embrittlement can be found. So the best annealing temperature range for disposal stress is ensured.
