Investigate the deformation mechanisms and microstructural development of produced titanium alloys – A review plasma sintering technology

Abstract

Abstract Titanium and its alloys possess excellent properties in the form of high strength-to-weight ratio, high fracture toughness, and high elevated temperature strength and are exceptionally resistant to corrosion. Many researchers have since investigated the morphology and the mechanical and corrosive properties of Ti6Al4V alloy reinforced with various ceramic particulates such as SiC, TiC, TiB2, Al2O3, Si3N4, Y2O3, B4C, etc. Titanium and its alloys may have good fatigue, high strength, and good oxidation and corrosion resistance properties, they had a wide application in aero/space and power generation industries. Ti-alloys are excellent structural materials, which fulfil the requirements of lowering fuel costs. Frequent use of Ti-alloys, moving towards the advancement of the next-generation engines. And it is not only reducing the structural weight but also helping in improving the safety standard. The present study includes the preparation of Ti and its alloys by the Spark Plasma Sintering process, which appears to be a promising route to produce Ti-alloys for structural applications. However, owing to the short duration of the process, the diversity and control of microstructures are limited concerning other processes. Though it is this short duration of the process which attributes several advantages at the same time such as producing refined microstructure ensuring rapid turnaround and low-cost. The microstructural evolutions of the synthesized sample were evaluated with the help of a scanning electron microscope (SEM). The phases present in the fabricated sintered composites were observed by an energy-dispersive X-ray diffractionspectrometer (XRD). These efforts may help in developing new alloys and their applications especially for Ti-alloys in aero/space engine in multiple performances such as strength, toughness, creep resistance, fatigue life, and other properties.
