Five high damping alloys, including TiNi, CuAINi,
CuZnAl, CuMn and FeCrMo, were heat treated to produce
optimum damping conditions. The strain dependence of
specific damping capacity was established using the resonant
dwell technique. The results were compared with those of
past investigations. For the CuAINi alloy, six different
heat treatment conditions were considered. The CuAINi
specimens were cold worked to determine the effect on
damping. An industrial survey was conducted to determine
the practicality of shipboard application of these alloys.
A comparison of the advantages/disadvantages of each alloy
was accomplished and recommendations were made for further
study
