Microalloying effects on the microstructure and kinetics of nanoscale precipitation in Ni-Al-Fe alloy

► Nanoscale α-phase precipitates in β-matrix promote precipitation hardening. ► Matching of β-phase microhardness and saturation magnetization of alloys. ► Magnetically assessed time-temperature-transformation diagrams. ► V microalloying improves stability of finely precipitated microstructure.
