Effects of annealing temperature on dealloying of Ti–Cu Alloy
Source abstract
Abstract
Abstract A combined annealing–dealloying method is applied to process Ti 33 Cu 67 alloy ribbons. This paper discusses the formation mechanism of nanostructured TiO 2 . With the increase of annealing temperature, phase segregation occurs and intermetallics of TiCu 3 and Ti 3 Cu 4 emerge. Multilayer TiO 2 and sea-urchin-like rutile TiO 2 were obtained by dealloying amorphous and crystalline ribbons in 65 wt.% HNO 3 solutions, respectively. The original shape of the ribbon can be maintained by the as-dealloyed 550 °C (and 600 °C) annealed ribbons and they possess good mechanical integrity. In addition, sea-urchin-like TiO 2 can slightly improve the photocatalytic performance of the degradation of methyl orange.
