摘要

The V-4Cr-4Ti alloys of SWIP-4 series were aging treated in different temperatures; the results showed that aging strongly influenced the mechanical properties of the alloy, and an optimized aging way was recommended. Microstructure observation indicated the strengthening of the alloy might due to the precipitation in the aging process, while the comparison of hardening between the specimens from SWIP-4 and NIFS-Heat-2 also indicated Oxygen might accelerate the response of the hardening.
