The thermal and electrical properties of shape memory alloys (SMA)are known to be different in their austenitic and martensitic phases. Thispaper addresses the determination of the phase-dependent heat capacity,thermal conductivity and electrical resistivity of a SMA wire. While the heatcapacity measurements are relatively straightforward using a differentialscanning calorimeter, the determination of the thermal conductivity and theelectrical resistivity are more difficult in view of the possiblenon-uniformity in the material state of a SMA wire during a phasetransformation. Experimental procedures are developed and used to determinethese properties in either phase and, along with a previously developedfinite-element code accounting for the non-uniform material states, theaustenite and martensite properties are determined from the experimental data.For the SMA wire tested, the thermal conductivities of the austenite andmartensite phases are determined to be2.8×10-2J(mmSK)-1and1.4×10-2J(mmSK)-1respectively, adifference of 100. The electrical resistivities of the austenite andmartensite phases are determined to be8.371×10-4mmand9.603×10-4mmrespectively, a difference of about14
