Dynamic Shear Modulus Measurements with Four Independent Techniques in Nickel-Based Alloys

Experimental results are presented, on a round-robin basis, to study the effect of vibrational frequency on the dynamic shear moduli of two metals, Inconel 600 and Incoloy 907. Four separate laboratories, each using a different experimental technique, obtained results over the nominal frequency range of 7 kHz to 10 MHz. A brief discussion and comparison of the four techniques, both resonant and pulse, are included. No significant differences were observed for each alloy's modulus over this frequency range.
