N2 - The influence of iron on phase evolution and tensile strength on metastable Ti-10Mo alloy is explored in this research work. Binary (Alloy A) and ternary (Alloy B) were Processed using the Amazement re-Powder melting system at the high inert environment, the melted ingots were further processed by solution treating in a muffle furnace at 1100 C and subsequently quenched in ice-brine water. The water-quenched alloys were evaluated for phase constituents and mechanical properties utilizing an X-ray diffractometer (XRD), optical microscope (OM), Tensile test, and micro-hardness respectively. Peaks of β + α″ + ω phase were distinctive in the XRD patterns of both Alloy A and Alloy B. OM micrographs of Alloy A showed β equiaxed grains and acicular structure within the grain and along the grain boundaries. The tensile strength of Alloy A was recorded as 701.40 MPa and that of Alloy B was 789.21 MPa. The yield strength decreased from 586.06 MPa in Alloy A to 504.43 MPa in Alloy B. The Elastic modulus of the studied alloys after water quenching decreased slightly from 116.81 GPa to 103.04 GPa. Alloy A showed better ductility with 23% elongation, whereas Alloy B demonstrated a lower elongation of 17%. Micro-Vickers hardness was higher in Alloy B due to smaller grains as compared to low hardness in Alloy A.
