Microstructure and hardness of spray-formed chromium-containing steel tooling Academic Article

abstract

• The microstructure and hardness of a spray-formed chromium-containing tool steel H13 were studied. There is very little porosity in both as-spray-formed samples and spray-formed samples following heat treatment. The microstructure in the as-spray-formed material is characterized by proeutectoid carbides, lower bainite, martensite, and retained austenite. Spray-formed H13 aged at a given temperature exhibits higher hardness than commercial H13 conventionally heat treated and tempered at the same temperature. The microstructures and hardness are rationalized on the basis of numerical analysis. 2006 Acta Materialia Inc.
