This paper develops a general expression for the specific rate of heat dissipation (SRHD) - ability of a material to dissipate an applied thermal load per unit surface temperature rise- of metals. The expression incorporates the variation in each of the thermal diffusivity and the thermal conductivity of the material with temperature elevation. It is shown that the general expression for SRHD is a super position of three functions which represent the competing effects of the room temperature thermal properties and their respective variation with temperature. Such expression is believed to facilitate parametric studies which investigate the effect of heat accumulation on the transition of wear mechanisms.
