Abstract: | Copper-whiskers with different orientations were excited in flexural vibrational modes. From the resonance frequencies and the cubic compressibility, the elastic constants cik of copper were determined. The results are in good agreement with values obtained by other authors using other methods with macroscopic single crystals of copper. No enhancement of Young's modulus, reported recently in thin metallic films, was seen in Cu-whiskers. |
