TL;DR: Powder metallurgy (PM) of titanium is a potentially cost-effective alternative to conventional wrought titanium as mentioned in this paper, which examines both traditional and emerging technologies, including the prod...,.

TL;DR: In this paper, a review of the fatigue properties of Ti-6Al-4V alloys made by different AM technologies and post-fabrication treatments were compiled and discussed to correlate with the materials' characteristic features, primarily surface roughness and porosity.

TL;DR: In this paper, single crystal titanium nitride powder was used to fabricate a single-crystal nitride film using a vacuum kinetic spray (VKS) process, which revealed an elastic-to-inelastic transition of the particles at high strain rate and high pressure induced by hypervelocity impact, which was considered vital for grain refinement and film growth.

TL;DR: In this article, high density powder metallurgy (PM) Ti-6Al-4V alloy, with a finer prior-β grain size, was achieved by vacuum sintering of TiH2 compacts at the β-transus (1010°C) temperature, taking advantage of the accelerated selfdiffusion.

TL;DR: In this paper, multiple mechanisms of fatigue crack initiation from pores leading to short-term and long-term fatigue life have been observed in a powder metallurgy (PM) Ti-6Al-4V alloy made by the hydrogen sintering and phase transformations (HSPT) process.
