Thus far, the joining of Nitinol alloys has been studied extensively using laser welding. Here, we studied the weldability of powder metallurgy (PM) Ti–51 at %Ni alloy by friction stir welding (FSW) via microstructural, superelasticity and mechanical property evaluations. The FSW welds were produced...
