摘要：

Using single crystals of a Fe - 28% Ni - 17% Co - 11.5% Al - 25% Ta (at.%) alloy, oriented for tensile loading along the [001] direction, the shape-memory (SME) and superelasticity (SE) effects caused by reversible thermoelastic martensitic transformations (MTs) from a high-temperature fcc-phase into a bctmartensite are investigated. It is demonstrated that the conditions necessary for the thermoelastic MTs to occur are achieved by aging at 973 K within the time interval (t) from 0.5 to 7.0 hours, which is accompanied by precipitation of the gamma'-phase particles, (FeNiCo)(3)(AlTa), whose d < 8-12 nm. When the size of the gamma'-precipitates becomes as large as d a parts per thousand yenaEuro parts per thousand 8-12 nm, the MT becomes partially reversible. The physical causes underlying the kinetics of thermoelstic reversible fcc-bct MTs are discussed.
