Effect of Quenching Temperature on the Mechanical Properties of Cast Ti‐6Al‐4V Alloy

並列摘要


Ti‐6Al‐4V alloy is a workhorse of titanium industry; it accounts for about 60 percent of the total titanium alloy production. The high cost of titanium makes net shape manufacturing routes very attractive. Casting is a near net shape manufacturing route that offers significant cost advantages over forgings or complicated machined parts. However, the disadvantage of the as‐cast titanium alloys, like other cast metals, is that the heat treatment remains only a limited option for improvement of their properties. The objective of this work was to study the effect of water quenching on mechanical properties of cast Ti‐6Al‐4V alloy. Tensile, hardness and charpy impact toughness tests were performed. The results showed that the final properties of cast Ti‐6Al‐4V alloy are highly dependent on the quenching temperature.
