Electropulses induced direct aging and ultrafast precipitation in additive manufactured 15-5 PH stainless steel
Periodic electric current pulses, i.e.electropulses, were applied on selective laser melting prepared 15-5 precipitation hardening stainless steel for direct aging.Traditional aging treatment typically takes hours to achieve peak hardening and could induce reverted austenite.Herein, electropulsing treatment on as-built sample can dramatically reduc
