Notes:
Solution nitriding and aging treatment were applied to Ti-4mass%Cr alloy in order tofabricate a ductile high-nitrogen titanium alloy with fine (α + β) structure. The solution-nitridedspecimen with[removed info]α’ martensitic structure was significantly hardened by solid solution strengthening bythe absorbed nitrogen. During the aging treatment, fine β grains with a size of 1 microns in thicknessprecipitated along the martensite-plate boundaries. Although the specimen was softened to someextent after the aging treatment, the hardness is kept much higher than that of the aged Ti-4mass%Cralloy without solution nitriding. This indicates that the nitrogen is still in solid solution of α phaseeven after the aging treatment, and contributes to strengthening of the fine-structuredTi-4mass%Cr-N alloy
