Abstract Scope |
Advancements in the development of computational tools continue to increase the scope of modeling capabilities and change the fundamental aspects of alloy design. The ability of finite element method (FEM) modeling to capture fundamental stress and strain interactions at multiple length scales makes it a useful tool for analysis of micromechanical phenomena such as stress transfer, yielding behavior, etc. within multi-phase metallic structures. This work utilizes FEM models of microstructures as a tool for optimizing steels for improved mechanical performance by analyzing the effects of ceramic or intermetallic particulate reinforcements. These models are used to predict the effects of changing morphologies, distributions, and volume fractions within an austenitic matrix. FEM predictions can be used as part of an iterative integrated computational materials engineering (ICME) alloy design process to reduce requirements of experimental iteration and significantly reduce the time required to develop new alloys to meet challenging design requirements. |
