Kinetic of Martensite Transformation in a Cu-13wt.%Al-4 wt.%Ni Shape Memory Alloy
Keywords:
Cu-13 wt.%Al-4 wt.%Ni shape memory alloy, differential scanning calorimetry, JMA model
Abstract
In this paper we present some results was obtained on the Cu-13 wt.%Al-4 wt.%Ni shape memory alloy. This alloy was elaborated by a classic melting method starting at pure metals. A DSC analysis was made for quenched sample cut from 4 mm diameter hot extruded wires. The results confirm thermoelastic transformation and provide for further application the critical temperatures for martensitic transformation.
