Abstract

Resonant ultrasonic spectroscopy was used to measure the orthorhombic elastic constants of rolled, polycrystalline plates of Cu, Cu - 5% Zn, and Cu - 15% Zn. The experimental results were in good agreement with theory for the Cu and the Cu-15% Zn materials. The agreement was not as good for the more anisotropic Cu-5% Zn material, especially for the in-plane compressional constants C₁₁ and C₂₂. The ultrasonically derived W's were compared to those optained from neutron measurements for the Cu-Zn alloys. Pole plots based on the two types of measurements, using W₄₀₀, W₄₂₀ and W^d440, were in excellent agreement for the 15% Zn material, and in qulaitative agreement for the 5% Zn material. The results support the idea that acoustic methods can be used to measure the low-order W's in polycrystalline materials.
