Abstract

Several properties with a thermoelastic phase transformation, the so-called shape memory effect, were studied in rapidly quenchd melt-spun Ti₅₀Ni_50-xCu_x (x = 0-20 at.%). By taking account of the improvements in several characteristics such as the large ductility (i.e. 180° bending ability), narrow transformation temperature range δT( = A_f - M_f) and high thermal energy conversion ability ν, it can be concluded that the merit and functional superiority of rapidly quenched melt-spun TiNiCu ribbon exist especially in the range of copper contents over 10 at.% in comparison with the conventionally manufactured (i.e. melting-mechanically worked) material.
