Influence of high heating rates on evolution of oxides on directed laser energy additively fabricated IN718

npj Materials Degradation, 2021
The effect of non-isothermal treatment in oxygen-containing air, via heating rates of 10, 50, and 1000 °C/min until 1000 °C followed by furnace cooling to room temperature on oxides formed on directed laser energy additively fabricated IN718 was studied.
