Journal ArticleDOI
Enhanced fatigue behavior of powder metallurgy Ti–6Al–4V alloy by applying ultrasonic impact treatment
TL;DR: In this paper, the effect of severe plastic deformation induced by multiple sliding impacts by the specimen surface produced at ultrasonic impact treatment (UIT) on the stress-controlled fatigue response of the powder metallurgy Ti-6Al-4V alloy is studied.
Journal ArticleDOI
Diffusion during Powder Metallurgy Synthesis of Titanium Alloys
TL;DR: In this article, a blended elemental press-and-inter powder metallurgy approach using hydrogenated titanium powder was used to synthesize uniform, nearly dense material with reduced grain size, at relatively low temperatures and short time.
Journal ArticleDOI

Orest M. Ivasishin,K. A. Bondareva,V. I. Bondarchuk,O. N. Gerasimchuk,D. G. Savvakin,B. A. Gryaznov +5 more
TL;DR: In this article, the fatigue-resistance characteristics of Ti-6Al-4V alloy synthesized by the simplest powder metallurgy method involving the processes of pressing and sintering of blended elemental titanium hydride-based powders were studied.
Journal ArticleDOI
Influence of grain size, aging conditions and tension rate on the mechanical behavior of titanium low-cost metastable beta-alloy in thermally hardened condition
TL;DR: In this article, the effect of aging on the performance of TIMETAL-LCB was studied, showing that aging caused an increase in strength and decrease in ductility parameters as compared to initial single-phase metastable β condition with two different β grain sizes.
Journal ArticleDOI
The effect of microstructure on porosity healing mechanism of powder near-β titanium alloys under hot isostatic pressing in α + β-region: Ti-10V-2Fe-3Al
TL;DR: In this paper, the authors studied the porosity healing in the Ti-10V-2Fe-3Al alloy obtained by powder metallurgy and found that the dislocation density after HIP treatment mainly increased in the interphase boundaries due to the action of hydrostatic stresses.
