説明
Rod-form single crystals of Fe-19.43%Cr alloy 3 mm in diameter and 12 cm in length were prepared, and measurements of the thermal expansion and Young’s modulus in the temperature range −150° to 250°C and the rigidity modulus at 20°C were carried out by means of dilatometer, a vibrator-controlled oscillator system and the torsion pendulum method, respectively. The data calculated from these measured values, showed that the Young’s moduli at 20°C were 14.22×105, 22.23×105 and 27.37×105 kg/cm2, and the rigidity moduli at 20°C were 11.36×105, 7.21×105 and 6.43×105 kg/cm2 in the ⟨100⟩, ⟨110⟩ and ⟨111⟩ directions of the single crystals, respectively, the elastic anisotropy being not so large. The Young’s modulus in the ⟨111⟩ direction exhibited a small minimum at 10°C and a small maximum at about 110°C with increasing temperature, while the Young’s moduli in the ⟨100⟩ and ⟨110⟩ directions decreased monotonously. The mean temperature coefficients of Young’s modulus at 10°∼110°C were −32.77×10−5, −9.85×10−5 and +4.71×10−5 in the ⟨100⟩, ⟨110⟩ and ⟨111⟩ directions, respectively. The calculated value of Young’s modulus for a polycrystal agreed fairly well with the measured one for the polycrystal specimen prepared by melting.
