The Influence of the Soaking Temperature Rotary Forging and Solution Heat Treatment on the Structural and Mechanical Behavior in Ni-Rich NiTi Alloy.The structural and thermophysical characteristics of an Ni-rich NiTi alloy rod produced on a laboratory scale was studied.  The soak temperature of the solution heat-treatment steps above 850 °C taking advantage of the precipitate dissolution to provide a matrix homogenization, but it takes many hours (24 to 48) when used without thermomechanical steps.  Therefore, the suitable reheating to apply between the forging process steps is very important, because the product's structural characteristics are dependent on the thermomechanical processing history, and the time required to expose the material to high temperatures during the processing is reduced.
