Martensitic transformation and mechanical behavior of porous Ti-50.0 at % Ni alloy, fabricated by self-propagating high temperature synthesis at different temperature

A study of temperature annealing on the crystalline structure, the kinetics of martensitic transformation and the mechanical behaviour in the porous Ti-50.0 at % Ni alloy produced by self-propagating high-temperature synthesis at different pre-heating temperatures was carried out. It was found that annealing the porous TiNi alloy in the temperature range of 573 K to 773 K may be used as an effective tool for producing variations in the properties of these objects. An increase in the fraction during annealing results in a decrease in the concentration of Ni in the TiNi phase and an increase in the TiNi fraction that undergoes martensitic transformation.
