Fundamental Studies on High Temperature Deformation Recrystallization, and Grain Growth of Two-Phase Materials.
Abstract
Two-phase materials are technologically important because optimum properties can be obtained by a proper combination of the two phases. Among these materials, two phase Titanium alloys are of particular interest for high temperature aerospace applications. However, there is a lack of understanding in the areas of high temperature deformation, recrystallization and grain-growth behavior of two-phase alloys in terms of the properties of the component phases. Such an understanding is essential to develop new titanium alloys with greater high temperature strength and stability for high temperature applications. The lack of understanding is due to the complex deformation behavior of these two-phase materials. Whenever a material comprising two or more phases is subjected to stress, the component phases deform differently and this results in inhomogeneous strain and stress distributions. In addition, interaction stresses develop as a result of interactions between the deforming phases. For these reasons, the deformation behavior of two-phase materials cannot be explained by the simple law of mixture rule.
