dc.description.abstractA research program has been completed on the dynamic elastic modulus measurements for several nickel and iron aluminide based intermetallics. The PUCOT (piezoelectric ultrasonic composite oscillator technique) was used for this purpose. Stress waves generated by the PUCOT were used to resonate the samples at ultrasonic frequencies. Longitudinal measurements were made at 100 kHz and the torsional measurements were made at 80 kHz. Tests were conducted from room temperature up to 1100'C. The elastic behavior in this interval was studied. Damping and strain amplitude data were obtained simultaneously with the elastic constants for each specimen at all temperatures. Arrhenius plots were drawn from the temperature and damping data. Activation energies were determined for all specimens tested. The Young's and torsional modulus data obtained in the present research were compared with those already available for similar intermetallic compounds and alloys.en
