Microstructure analysis of element W in improving the Ni–P deposit thermal stability

Microstructure analysis of element W in improving the Ni–P deposit thermal stability

Amorphous Ni–3.81 wt.%W–12.40 wt.%P deposit showed two crystallization exothermic peaks while amorphous Ni–12.35 wt.%P deposit presented one. Formation of the two exothermic peaks and the related influencing factors were investigated through TEM, DSC and XRD. The solid solution and pinning effect of...
