Microdefects and electron densities in NiTi shape memory alloys studied by positron annihilation

The microdefects and free electron densities in B2, R and B19′ phases of Ni 50.78Ti 49.22 alloy were studied by positron lifetime measurements. Comparing the lifetime parameters of the Ni 50.78Ti 49.22 alloy measured at 295 K and 225 K, it is found that the free electron density of the R phase is lo...
