Effect of annealing temperature on microstructure and properties of Ti 3Al-5Fe-1Cr titanium alloy golf club

Titanium alloy is a common material of golf clubs. Ti-3Al-1-5Fe-1Cr titanium alloy is a relatively successful golf club material because it enhances the anti-elasticity of golf clubs. The Ti-3Al-1,5Fe-1Cr dual phase titanium alloy was studied. The microstructure and mechanical properties of the alloy after annealing treatment were studied. The effects of annealing treatment on the microstructure, hardness, strength, plasticity and toughness of the alloy were clarified. After annealing treatment, the microstructure of the alloy is composed of cluster-like staggered lamellar α phase and β phase. When the annealing temperature is 850 °C, the hardness of the alloy is the highest 447 HV, the tensile strength is the highest 958 MPa, and the elongation after fracture is 16 %.
