摘要:
The isothermal internal friction (IF) behavior of dual-phase Ni52Mn32In16 magnetic shape memory alloy was investigated by dynamic mechanical analysis. The contribution of the isothermal IF to the overall IF peak is close to 90%. This high isothermal IF is obtained over a large working temperature range of 88 degrees C, which is broadened by the concurrence of the martensitic transformation and the intermartensitic transformation. An strong hindering effect on structural transformations is identified by microstructural observations. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
