Quenching and Hot Isostatic Pressing of Additively Manufactured Tool Steel
A maraging grade and a modified H13 type tool steel were used as testing materials to study the possibility of healing printing defects while combining a solutionizing/hardening treatment to the components. Extensive mechanical testing and microstructural analysis showed that the high-pressure heat treatment can stabilize retained austenite in maraging grades, but has no effects on the aging kinetics. A HIP temperature of 850°C is not sufficient to heal printing defects in highly defective maraging components, while 1020°C were sufficient to fully heal a modified H13 component. Increasing HIP temperature over 1140°C causes lower impact toughness, due to grain growth and/or precipitation and growth of MnS.
