“…It is important to note that the obtained results of vacancies concentration (see Table 2) are lower than 1.0%, which means that thermal defects are minimal (these results are lower than the experimental error). Among the mechanisms that can produce a lattice parameter reduction [26], vacancies are one of the most common defects during the casting process. Nevertheless, due to the low range of vacancies concentration obtained for all alloys, it is demonstrated that by using this process under vacuum conditions and the applied heat treatments under He atmosphere, a considerable thermal defects reduction can be obtained.…”

In this investigation, Cu–Ni alloys with different aluminum additions were synthetized under a vacuum atmosphere to reduce the material density. Annealed alloys in a He atmosphere with low aluminum concentration exhibited a coarse dendritic structure, while samples with high aluminum concentration exhibited a refined dendritic structure. Structural defects analyses have shown relatively low vacancy concentrations. Hardness evaluations indicated an increment by approximately 5 times i.e., 370 HVN, more than that for the alloyed samples compared with the as-cast and unalloyed samples. Compression tests have shown a noticeable strengthening improvement (360 MPa), mainly in samples heat treated with 10 at.% Al, while samples with 5 at.% Al showed an acceptable resistance (270 MPa) as well. In general, the sample with 10 at.% Al presented the best performance to be considered as potential structural material.
