Abstract
Crack-healing experiments via both conventional heating and microwave heating were performed on Vickers-indented specimens of polycrystallin e alumina (Coors ADS-995). For the entire temperature range included i n this experiment (1510-1742 K), the crack-healing rate was enhanced f or microwave heating compared to conventional heating. The microwave c rack-healing data were described well by a diffusive mass transport mo del given by Stevens and Dutton. (C) 1997 Elsevier Science Ltd.
