【摘要】 应用X射线衍射极密度测定法和Warren-Averbach Fourier分析法研究了冷变形及其固溶处理和时效处理后含铈马氏体时效钢织构与亚结构。实验表明,形变织构具有遗传性;亚结构具有时效稳定性;力学性能表现出明显的各向异性。文中讨论了形变织构遗传性成因,强化和力学性能关系。更多还原

【Abstract】 The texture and fine substructure of cold rolled and solution aging treated maraging steel con-taining cerium have been investigated using X-ray pole density measuring method and Warren-Averbach Fourier analysis. The experimental results indicated that deformed texture is heritable.The cold-rolled martensite matrix has fine substructure which is stable after solution and aging tr-eatment. The reason of inheritance of deformed texture and relation between strengthening andmechanical anisotropy are discussed.更多还原
