| Abstract Scope |
Ti is widely used in the aircraft industry, whereas the degradation of mechanical properties and oxidation resistance under high temperatures and low machinability limit its application. The thermally stable element alloying and the improved fabrication methods enhance the properties of Ti-based alloys. In this study, one novel Ti-W system is designed and fabricated using arc melting and sintering. The A2-B2 core-shell system of arc-melted alloy provides multi-scale strengthening mechanisms, showing potential for structural alloy application. The sintered alloy has homogenized ultra-fine grains with many metastable phases like FCC Ti and Ti2Fe induced via the plastic deformation stage, contributing to the extremely high hardness and elastic modulus, which is competitive in the Ti-based alloys. This novel Ti-W alloy system holds significant prospects in aircraft engineering, leading to the application of more extreme mechanical properties. |
