Year: 2024

Type: article

Abstract: Titanium and titanium alloys exhibit low density, high strength and excellent corrosion resistance, and have become workhorses in modern aerospace and chemical processing industries. Recently, Ti-6Al-4V alloy has been manufactured through metal injection molding (MIM). MIM is widely utilized in various manufacturing industries due to the near-net-forming process, especially in the preparation of difficult-to-deform high-temperature alloys. Sintering temperature is vital to ensuring good tensile mechanical properties. In this work, Ti-6Al-4V alloy was sintered under various sintering temperatures, from 1150 to 1250 °C. The effect of sintering temperature on the mechanical properties was evaluated. The tensile test results exhibited that a yield strength of 896.35 MPa, an ultimate tensile strength of 980.83 MPa and plastic elongation of 9.61% were produced at 1150 °C for 4 h; a yield strength of 877.23 MPa, an ultimate tensile strength of 981.92 MPa and plastic elongation of 7.74% were produced at 1200 °C for 4 h; and a yield strength of 923.33 MPa, an ultimate tensile strength of 1002.24 MPa and plastic elongation of 6.57% were produced at 1250 °C for 4 h.
