Thermodynamic
properties of metastable Mn-Cu
alloys in the low-temperature FCC-FCT
transformation range
Abstract
A
pioneer study of partial thermodynamic functions of manganese in the FCC-FCT
transformation and relaxation of quenched
and annealing alloys of Mn-Cu
system has been performed. The method of emf measurement of concentration
chemical cells with electolyte glicerine solutions has been
applied. The variation of the
chemical potential with the temperature matches the multi-stage character of the
transformation. Multi-stage
thermocycling leads to the relaxation of metastalbe FCC and FCT
alloys. For the first time the metastable FCC - FCT equilibrium temperature To
for Mn60Cu40 alloy has been experimentally determined.
