摘要
10 Mn Ni Cr钢是一种高强度 (σs≥ 4 4 0 MPa)、高韧性和良好焊接性的低合金焊接结构钢。研究了粒状贝氏体组织对 10 Mn Ni Cr钢力学性能的影响。结果表明 ,在连续冷却过程中形成的粒状贝氏体显著降低钢的低温韧性。通过回火处理使粒状贝氏体充分分解 。
The 10MnNiCr steel is kind of low alloyed steel for welded structure with high strength(σ s≥440 MPa), high toughness and good welding performance. The influence of granular bainite on mechanical properties of microalloyed 10MnNiCr steel was studied. The result shows that the granular bainite is formed in the period of continuous cooling. The formation of granular bainite obviously decreases the low temperature toughness of the steel. The toughness of the steel can be apparently improved by tempering treatment, which makes the granular bainite decomposed sufficiently.
