摘要
Entropy changes during beta(1) <----> beta'(1) and beta(1) <----> gamma'(1) transformations in Cu-14.3Al-4.1Ni (wt.%) and Cu-14.1A1-4.2Ni (wt.%) single crystals were obtained, in order to evaluate changes on the relative stability of the metastable phases involved. These values were determined by DSC measurements and isothermal tensile tests performed at different temperatures. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
