Effect of Aging Temperature on Microstructures and Properties of Ti6242S Alloy

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.
