摘要
采用14MnMoVN钢板,用弯板、时效状态与原始状态材料进行对比试验。研究了弯板时效及低温对比钢板断裂韧性的影响。发现弯板时效及低温使该钢板断裂韧性大幅度下降。
In the article, we studied the effect of the bending deformation, ageing and low temperature on the fracture toughness of the 14MnMoVN steel plate. We verified that bending deformation, ageing and low temperature ledto notably decreasing of the fracture toughness.
