Electropulsing assisted aging with ultrafast hardening rate for AerMet100 steel
Materials Science and Engineering: A（2022）
摘要
Carbide precipitation behavior is greatly improved for AerMet100 steel by high frequency electropulsing assisted aging (EAA). As a result, the EAA hardening efficiency of AerMet100 remarkably increased by ∼10 times compared with that of conventional furnace ageing. Fracture elongation exceeds 18% within 10 times of EAA peak aging time.
