Description

Precursor phenomena of thermoelastic martensite transformations of Fe3Pt have been studied by mechanical tests, X-ray diffractometry, transmission electron microscopy and neutron inelastic scattering measurements. The ordered austenite with an Ll2 structure becomes soft markedly at temperatures below 200 K. It was also confirmed that the TA mode along [011] directions of the alloy became soft at zone boundaries of the reciprocal space with approaching to the transition temperature. The observed precursor phenomena are considered to be related to the thermoelastic fcc-fct martensite transformation. (orig.)
