Enhancement of Microstructural and Hardness Properties of Commercially Pure Titanium (Ti-0.5Zn) by Thermomechanical Processing

Article Preview

Abstract:

Titanium alloys are widely used in the aerospace, biotechnology, automotive, energy, marine industrial constructions and components due to their high strength-to-density ratio, excellent fatigue/crack propagation behaviour and corrosion resistance. This study investigates the αβ phase transformation which Ti-0.5Zn alloy undergoes on being subjected to heat treatment with the aim of improving its properties and to enhance its industrial application. The β phase, with Widmatansttäten type growth was produced by heat treatment of the alloy in the temperature range of 800°C to 1000°C. The resultant microstructure and hardness of the alloy was also investigated. The result showed improved morphology evidenced by transformation from the equiaxed grains to more lamellar structures in the samples. Hardness property improved by 20% too.
