摘要：
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.
