SMA powder┃Fe–17Mn–5Si–10Cr–4Ni

Shape memory alloys fabricated by additive manufacturing, known as three-dimensional (3D) printing, , comparable the conventional fabrication method, such as casting and rolling, showed higher shape memory effect (SME).

The particle size distribution of our gas-atomized spherical Fe–17Mn–5Si–10Cr–4Ni (wt.%) shape memory alloy (Fe-SMA) powder for L-PBF process is 15-53um.

After a series of experiments conducted by R&D department of Truer, it has been proven that post-heat treatment on the microstructure and shape memory properties of printed partsby our 15-53um powders has some clear impacts, concluding the best combination of the post-heat-treatment temperature and time to the highest recovery strain is about 800 °C for 0.5 h.
