Fabrication of an isotropic Ti–3Al–8V–6Cr–4Mo–4Zr alloy with a combination of high strength and good ductility
A method on fabricating the Ti-3.09Al-6.66V-5.62Cr-4.54Zr-4.93Mo (Ti-38644) fasteners with high strength and good ductility was reported in this study, whose tensile property evades the strength–ductility trade-off dilemma in Ti-38644 alloys. The microstructure in present Ti-38644 alloy is mainly composed of equiaxial β grains with tiny α particles embedded in them. The microstructure is homogeneous without obvious textures, leading to an isotropic mechanical property. The present method to process Ti-38644 fastener is both cost-effective and readily scalable. The process discovered here is readily scalable at a low cost and might be conducive to industrial production and to be applicable to other Ti alloys fasteners.
