Abstract

In this study, new ultra-high strength Ti-alloys composing low cost common metals (i.e., Fe, Mn, Al, and Sn) are developed. In the present new alloys, the beta-phase was the predominant phase in the annealed condition and showed moderate tensile strength (UTS) in the range of 800 ÷ 950 MPa where the fracture strain was below 4 %. After sever cold rolling followed by aging treatments, the UTS of the alloys were greatly increased and achieved values higher than 1900 MPa where the elongation was less than 1 %. Further increase in the ductility of the alloys is possible with the proper heat treatments on the expense of the strength. The ultra-high strength of the present new Ti-alloys make them competitive to high specific strength alloys because of its good cold workability and low cost.
