Thermal-Expansion Studies of High-Damping Mn-Cu Alloys

  • D. K. Chatterjee
  • P. Venkateswararao


The thermal expansion of Mn-Cu alloys was measured in order to study the phase transformation and to assess the stability of the phases responsible for the high damping capacity observed in these alloys. High internal stresses build up during these transformations, and a large volume contraction could provide the necessary mechanism for absorption of vibrational energy.
