This is an investigation of the mechanical anisotropy in hexagonal close-packed metals deformed by multiaxial stresses. The anisotropic creep behavior, the crystallographic textures, and correlations between texture and materials properties will be determined, including the effects of other material variables such as slip behavior and microstructural characteristics. These studies should permit the development of more predictive models of micromechanisms of creep in these anisotropic metals.

本文研究了六边形密排金属在多轴应力作用下的力学各向异性。将确定各向异性蠕变行为，晶体织构以及织构与材料性能之间的相关性，包括其他材料变量（如滑移行为和微观结构特征）的影响。这些研究应该允许开发更多的预测模型蠕变的微观机制在这些各向异性金属。
