The 4W alloy exhibits a yield strength of 810 MPa, an ultimate tensile strength of 891 MPa, and an elongation-to-failure of 26.3%. The improved yield strength is attributed to the combined effects of solid solution strengthening, grain boundary strengthening, dislocation strengthening, and precipitation strengthening. Detailed analysis revealed that the ductile face-centered cubic matrix effectively suppresses the propagation of microcracks originating from the hard and brittle precipitates. Furthermore, dislocation-precipitate/grain boundary interactions, nanoscale deformation twins, and deformation-induced martensitic transformation collectively improve the work-hardening capacity.
