Effect of direct aging on the microstructure and sustainable milling performance of L-PBF 17-4 PH stainless steel
This study investigates the influence of direct aging (DA) and cooling/ lubrication strategies on the milling performance of 17–4 PH stainless steel (SS) fabricated via laser powder bed fusion with a comparative assessment against commercially obtained 17–4 PH SS. Direct aging was performed at 580 °C for 1, 2, and 3 h...
