Abstract Scope |
Cu-Ti alloys exhibit comparable mechanical properties to Cu-Be and represent an excellent alternative for mechanical applications, given that the use of Cu-Be alloys is progressively restricted due to the carcinogenic nature of Be. Although its electrical conductivity is considered inferior to Cu–Be alloy, its mechanical properties are comparable, especially exhibiting superior high-temperature performance. Like Cu-Be, the Cu-Ti alloys are age-hardenable. However, their electrical conductivity is considerably inferior to that of pure copper. The addition of Ni has been found to increase the alloy conductivity, although this is at the expense of mechanical properties. In this study, we present a comparative characterisation of Cu-3Ti, Cu-3Ti-2Ni and Cu-3Ti-5Ni vacuum inert gas atomised (VIGA) powders intended for powder-bed based additive manufacturing applications, discussing the influence of the melt composition on powder microstructure, chemical composition and rheological properties. |
