Abstract
Spark plasma sintering of Ti50Ni50 nano-powder at a temperature of 800°C produced specimens showing good shape memory effect and density. Below this temperature, specimens have high porosity but with apparent shape memory effect. By contrast, the specimens sintered at higher temperatures have bulk density, but experienced extensive oxidation with the resulting loss of the shape memory effect.
