Description
Measurements of thermal expansions and Young’s moduli at −150∼500°C have been carried out for single crystal specimens, 3 mm in diameter and 120 mm long, of Co-Elinvar. At the same time the rigidity modulus of a polycrystal of the same alloy has been measured at room temperature. The Young’s moduli at 20°C obtained are 9.45×105, 19.47×105 and 30.12×105 kg/cm2 in the ⟨100⟩, ⟨110⟩ and ⟨111⟩ directions, respectively, while the rigidity moduli are 16.71×105, 5.93×105 and 4.88×105 kg/cm2 in the three principal directions, respectively. In both cases, the elastic anisotropies are very large. The Young’s modulus vs temperature curves in the three principal directions show a small maximum at temperatures below the magnetic transformation point. The mean temperature coefficients of Young’s moduli at 0∼40°C in the three principal directions are e⟨100⟩=−0.47×10−5, e⟨110⟩=−3.40×10−5 and e⟨111⟩=−6.77×10−5, respectively.
