Fabrication of porous samples from a high-temperature Cu–Al–Ni–Mn–Nb shape memory alloy by freeze-drying and partial sintering

Shape memory alloys (SMAs) find important applications in many fields, including the biomedical, aerospace, and civil construction industries. The increasing interest in these materials arises from their mechanical properties such as shape memory effect, superelasticity, and damping capacity. In this work, porous samples of a Cu–Al–Ni–Mn–Nb alloy were successfully fabricated. It is the first time that porous samples of this alloy are obtained by...
