ELASTIC ANISOTROPY AND ITS TEMPERATURE DEPENDENCE OF THE SINGLE CRYSTAL OF FE-19.43% CR ALLOY

Abstract

The thermal expansion and Young's modulus in the temperature range - 150 to 250 C and the rigidity modulus at 20 C of the alloy were measured by means of a dilatometer, a vibrator-controlled oscillator system and the torsion pendulum method. The calculated value of Young's modulus for the polycrystal agrees fairly well with the measured value for the polycrystal specimen prepared by melting.
