摘要The work prepared a typical Ni-17Mo-7Cr (wt.%)-based superalloy and investigated the effect of aging time on microstructure and mechanical properties of the alloy subjected to simulated heat-affected zone (HAZ) thermal treatment. After aging, many fine MoC particles are precipitated at the grain boundaries as well as in the grains. Regions with lamellar-like structures become larger, and many fine MoC particles are produced around them. The microstructural degradation caused by aging has limited influence on the alloy's high-temperature (800 A degrees C) mechanical properties. After exposure to the HAZ simulation, the alloy can still maintain excellent mechanical properties when aged at 800 A degrees C for different time, similar to the alloy that did not undergo the HAZ simulation.
