A periodic layer (PL) structure characterized with interval distribution of austenite for 17-4 PH steel is achieved by the laser direct metal deposition and aging. The synergism of strain partitioning hardening and austenitic transformation-induced plasticity contributes crucially to the excellent strength-ductility combination in the PL structured 17-4 PH steel.

通过激光直接金属沉积和时效实现了 17-4 PH 钢的以奥氏体间隔分布为特征的周期性层 (PL) 结构。应变分配硬化和奥氏体相变诱导塑性的协同作用对 PL 结构 17-4 PH 钢中优异的强度-延展性组合至关重要。
