The ultrahigh functional response of CuAlMnNb shape memory alloy by selective laser melting
In this study, the Cu-11.85Al-3.88Mn-1.6Nb (wt.%) shape memory alloy with low cost and a highly functional response was manufactured by selective laser melting(SLM). The effects of energy inputs (123–185J/mm3) on their microstructure, mechanical, and shape memory properties were investigated. It was...

| description | In this study, the Cu-11.85Al-3.88Mn-1.6Nb (wt.%) shape memory alloy with low cost and a highly functional response was manufactured by selective laser melting(SLM). The effects of energy inputs (123–185J/mm3) on their microstructure, mechanical, and shape memory properties were investigated. It was observed that all of the samples were composed of 18R and 2H martensite, and the nanosized (Cu, Mn)3Al3Nd4 phase was formed during selective laser melting(SLM). In addition, the good compressive fracture strength and strain were 1652Mpa, and 15.1% respectively. An excellent shape memory effect of 99.26% recovery ratio and 5.32% shape memory strain was obtained by SLM. |
