Hardness is one of the critical materials properties adopted for designing of engineering components which require high wear resistant. For engineering applications related to an elevated temperature service, materials hardness at the service temperature or/and temperature range is needed for engineering wear resistant simulation and design.
Ambient hardness of heat and wear resistance alloys can be associated with alloys’ thermal treatment condition. However, lack of information on the influence of thermal treatment parameters to hot hardness often induces challenges for a precision design including both materials selection and component geometric design. The effect of heat treatment on hot hardness of a tool steel (M2/J120V), two heat and wear resistant steels (J130 and J160), and an intermetallic strengthened alloy (J513) was investigated. As a comparison, an intermetallic matrix superalloy, Jonesite 19 was also evaluated.
This study manifested the basic need of hot hardness information of engineering materials for high temperature applications and, the database can be extended for future engineering simulation, modeling, and precision engineering design applications.
