Structural studies on Ti–Cu alloy obtained by high-energy ball milling

Abstract: Ti50Cu50 (at.-%) alloy has been produced from elemental Ti and Cu powders by high-energy ball milling in a planetary ball mill. Structural evolution of the alloy during milling and after subsequent heat treatment have been studied. It has been stated that high-energy ball milling of the investigated powder produces two nanocrystalline solid solutions: Cu(Ti) and Ti(Cu), both characterised by the fcc (Fm-3 m) structure. The transition of Ti structure from hcp (P63/mmc) to fcc (Fm-3 m) is observed during milling… Show more

“…To achieve enhanced sintered densities (reduced porosities) of BEPM-produced titanium alloys, preliminary activation of raw powders or powder blends by milling can be successfully used [ 18 , 19 , 20 ]. The same treatment is a potential way to improve sintered microstructures of TiB reinforced composites.…”

“…Já o deslocamento da posição dos picos está relacionado a deformações presentes nas redes cristalinas que foram potencialmente causadas pela MAE, a qual pode-se introduzir uma grande quantidade de defeitos no material devido às sucessivas colisões sofridas pelas partículas no decorrer desse processo. Outros trabalhos na literatura já indicaram estes mesmos efeitos, mostrando que a moagem altera os parâmetros de rede do material, cujos picos alargados e deslocados para 2-θ mais baixos encontram-se de acordo com o trabalho aqui proposto (DALY et al, 2006;PANEK;KAROLUS, 2019). Não foram observados picos de Cu nas amostras analisadas pela técnica de DRX.…”
