An Analysis of Relationships Between Behavior and Microstructure Constitution of Hot-Work Tool Steel
Influence of microstructure on mechanical behavior of hot-work steels is analyzed on submicro, micro, and macro scale. Except for suitable microstructure, phase distribution, and microstructure refinement, proper alloy chemistry and melting practice are important for hot-work steel properties. Methods of determination of working stress of hot-work steels have been presented. In optimization and selection of hot-work steels, proper failure criteria are based on predicted specific failure micromechanism of tools and dies in application. Failure micromechanisms have to be modeled and numerically defined in terms of time and temperature. Hot-work steel development has to be based on simultaneous optimization of materials properties and tool performance. In modern optimization and selection of hot-work steels, proper failure criteria have to be recognized based on probable failure micromechanisms in tool or die applications.
