摘　　要：The effect of cooling(laminar cooling)start temperature on the phase constitution was analyzed by quantitative metallography.The martensite/austenite(M/A)island distribution was fixed by colour metallography.The strength and uniform elongation of the steels were tested with quasi-static tensile testing machine.The in-coordinate deformation of the soft and hard phases was analyzed using FEM.The results indicate that when the cooling start temperature is 690 ℃,the mechanical properties are the best,meeting the requirements of X80 high deformability pipeline steel. 关键词：层流冷却协调变形力学性能管线钢 X80 显微组织温度定量金相分析
