Single Crystal Superalloys: Constitutive Equations and Computational Procedures

本研究是对镍基高温合金单晶高温变形机理的实验-分析-计算相结合的研究。特别注意材料的两相性质，非施密德剪切应力和潜在硬化对粘塑性变形行为的影响。三维本构关系的发展将有助于分析和设计由单晶制成的结构部件。//

The research is a combined experimental-analytical-computational effort to study high temperature deformation mechanisms in nickel-base superalloy single crystals. Special attention will be paid to two-phase nature of the material, the effects of non- Schmid shear stresses and latent hardening on viscoplastic deformation behavior. Three dimensional constitutive relations will be developed that will facilitate the analysis and design of structural components made from single crystals.//
