- Abstract
The impact of the heat treatments on the microstructure, high temperature hardness and wear performance at room and elevated temperature on a IN718 alloy fabricated via laser metal deposition (LMD) is investigated. It was found that the microhardness of the laser deposited IN718 alloy under different heat treatment conditions decreases with the increase of test temperature. Under various heat treatment conditions the wear rate of the laser deposited IN718 alloy at high temperatures is lower than that at room temperature. At room temperature the wear rate of the as-deposited IN718 alloy is higher than that of the heat treated samples. In contrast, at elevated temperatures the wear rate of the as-deposited IN718 alloy is lower than that of the heat treated samples.
