Interstitial elements in Ti–13Nb–13Zr alloy produced by powder metallurgy using hydride powders

Abstract: Absorption of interstitial elements during the processing of Ti-13Nb-13Zr alloy using hydride powders was investigated. Oxygen, nitrogen and carbon contents were quantified in the steps of hydriding and milling of powders and after sintering of green compacts. The influence of the hydriding treatment was analysed regarding the interstitial contents in the raw materials. Milling and sintering were evaluated according to a 3 3 factorial design considering the effects of milling time of titanium hydride from 1 to… Show more

“…The oxygen levels in Table 1 were obtained higher than the typically reported for Ti powders [2], especially for the fraction <45 μm. As discussed elsewhere [14], this was attributed firstly to the hydriding treatment of the Ti sponge, followed by the milling of the hydride powder. The nitrogen contents were also high (Table 1).…”

“…Henriques et al (2005) Adicionalmente, a fase α apresentou-se mais refinada nas amostras confeccionadas com o pó moído do que nas confeccionadas com o pó controle. Portanto, como esperado, a moagem levou a uma mistura mais homogênea e introduziu defeitos, os quais aumentaram a difusão dos elementos e permitiram maior refinamento da estrutura com o aumento da energia fornecida ao sistema por meio do aquecimento do material.…”
