Concurrent Effect of Melt-spinning and Severe Plastic Deformation on Shape Memory Alloy Ribbons by Simultaneous XRD and Electrical Resistivity Measurements

Research output: Book/ReportCommissioned report


The experiments have been performed on the TiNiCu shape memory alloy ribbons, in the as cast (AC), severely deformed: as mild (MSPD) and very (VSPD) deformed, and VSPD and annealed (VSPDA) state. The experiments were made in the beryllium dome, with the electric resistance vs temperature (ER) measurements performed using a Keythley 2010 multimeter. The heating and cooling was performed between - 100 and + 150 o C. The shape memory alloy ribbons have been mounted on silicon wafers and insulated using kapton foil. Not all the experiments on ER were successful, but it has been proven that the equipment can be use in conjunction with the XRD to identify the onset of the phase transition and to adjust the temperature interval between two measurements according to the development of the phase transition.
