| Abstract Scope |
As a specialty alloy manufacturer, Carpenter Technology uses various computational tools for alloy design as well as product development. Most widely used are CALPHAD based tools for equilibrium phase prediction, composition and heat treatment optimization, solidification/segregation and partition calculation). Finite element based modeling tools are used for design and optimize hot/cold working process. However, microstructure models find less utilization due to various reasons including computational cost, lack of available data, uncertainty, and specialized skills needed to setup and interpret results. We will share several case studies where alloy manufacturers could benefit from commercially relevant microstructure models. Examples include predicting recrystallization and grain structure after non-uniform multi-step hot working and heat treatment; predicting hot/cold cracking during material processing (liquation of low melting temperature phases, precipitation of hardening phases, localized plastic deformation and dynamic recrystallization); and stress relief heat treatment of additively manufactured high hardener content superalloys, etc. |
