ABSTRACT

The development of new metallic alloys is traditionally a very tedious process, which involves extensive experimental investigations by which composition and processing conditions are varied in a more or less erratic manner until the desired properties are achieved. The properties of metallic alloys depend on phases present, their composition and how they are geometrically arranged in the microstructure, involving structural elements on micro, nano and atomic scale. This chapter discusses the alloyneering methodology for alloy design. According to the alloyneering methodology, the alloy design process is performed in five stages depicted, they are: analysis; simulation; validation; mapping; and optimization. The chapter discusses computational thermodynamics, computational kinetics and phase-field modeling. Computational kinetics is a computational framework for solving problems related to phase transformations in metals and alloys. Phase-field modeling is a methodology, which allows the study of the thermodynamics and kinetics of interface migration and the associated microstructural evolution.
