The temperature dependence of Young's modulus and the shear modulus of polycrystalline alumina is given over the range of 25 to 1000 °C. Results are expressed in terms of the dimensionless ratio: modulus value at temperature divided by modulus value at 25 °C. These results are intended for use with Standard Reference Material No. 718 which is intended for calibration of apparatus used to determin elastic moduli of solids by a resonance technique. The worst agreement is 9.5 × 10 for the flexure and 19.1 × 10 for the torsion, between any two individual measurements, and we recommend these as the minimum acceptable limits in using the standards.
给出了多晶氧化铝的杨氏模量和剪切模量在25至1000°C范围内的温度依赖性。结果以无量纲比率表示：温度下的模量值除以25°C时的模量值。这些结果适用于标准参考物质718，该物质用于校准通过共振技术测定固体弹性模量的仪器。任意两次单独测量之间，弯曲的最大偏差为9.5×10，扭转的最大偏差为19.1×10，我们建议将这些值作为使用该标准时的最低可接受限度。
