Abstract:

Young's modui of elasticity E of three single crystals of cobalt prepared by the method of slow solidification were measured by a new microscopic method at room temperature. From E measured and the known value of compressibility of a poly crystal of cobalt, the Voigt moduli were calculated. The results are as follows S11=0.622×10_12cm/dyne S33=0.508×10-12cm/dyne S44=1.928×10-12cm/dyn S12=-277×10-12cm2/dyn S13=-0.163×10-12cm2/dyn The elastic anisotropy for Young's (E) and rigidity (n) modulus is E_??_/E_??_=1.22, n_??_/n_??_=1.03 respectively.
