The effect of thermal post-processing treatment on laser powder bed fusion processed NiMnSn-based alloy for magnetic refrigeration
Abstract
This study investigates the effects of heat treatment (HT) time (one, two, and three weeks) on the microstructure and magnetocaloric effect (MCE) of laser powder bed fusion (LPBF) NiMnSn alloys. Increasing the HT time improves chemical homogeneity, and decreases the local misorientation imparted by the LPBF process. This is also associated with an enhancement in the maximum magnetic entropy change (ΔS<sub>m</sub>) values around the martensitic transformation temperature (T<sub>M</sub>), which increases from 0.2 J kg<sup>−1</sup>K<sup>−1</sup> to 0.45 J kg<sup>−1</sup>K<sup>−1</sup> under 1 T applied magnetic field. However, theΔS<sub>m</sub>of the one-week HTed sample around the curie temperature (T<sub>c</sub>) (0.90 J kg<sup>−1</sup>K<sup>−1 </sup>at 315 K) is slightly lower than the two weeks and three weeks HTed samples (0.99 J kg<sup>−1</sup>K<sup>−1</sup> at 320 K, 0.94 J kg<sup>−1</sup>K<sup>−1</sup> at 320 K), respectively.
