Inhomogeneity of Room‐Temperature Elastocaloric Effects in NiTi Alloys Fabricated by Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT NiTi shape memory alloys are among the most promising solid‐state refrigeration materials. In recent years, additive manufacturing methods for producing difficult‐to‐machine NiTi alloys have gained increasing attention from researchers. This work successfully produces NiTi alloys with good superelasticity at room temperature via laser powder ...

Enhanced electrocaloric effect over a broad temperature range in lead‐free Na0.5Bi0.5TiO3‐based relaxor ferroelectrics via doping with Bi(Mg0.5Zr0.5)O3

IET Nanodielectrics, Volume 7, Issue 2, Page 59-67, June 2024.
(0.74‐x) Na0.5Bi0.5TiO3‐0.06BaTiO3‐0.2SrTiO3‐xBi(Mg0.5Zr0.5)O3 (abbreviated as NBT‐xBMZ) (x = 0, 0.02, 0.04, 0.06 and 0.08) lead‐free relaxor ferroelectrics were designed and prepared using a conventional solid‐state reaction method. Via doping with BMZ, an enhanced relaxor feature and a wider temperature range where multi‐phases coexist were achieved.
