【摘要】 研究时效温度下等轴组织的变化,对组织中等轴α相含量、大小及条状α相含量、大小进行定量化分析。根据组织参数的变化规律解释了不同热处理参数下拉伸性能的变化。表明近α合金Ti6242S的组织与性能之间存在着定量关系。更多还原

【Abstract】 The changes of equiaxed microstructure under aging heat treatment conditions were studied,and the microstructure parameters,which include the sizes and contents of equiaxed α phase and lamellar α phase were quantitatively analyzed.The tensile properties is explained by the variation of the microstructure parameters.The results show that a quantitative relationship of Ti6242S alloy near α exits between microstructure and tensile properties.更多还原
