Literature studies reveal apaucity of data on the Th-Zr system. Investigations on the Th-30Zr alloy and its synthesis, microstructure and characterization were carried out. The Th-30Zr alloy was characterized using X-ray diffraction, optical microscopy and SEM–EDS. The elastic properties of the Th-30Zr alloy were measured and showed that, alloying of zirconium increased the modulus of elasticity. Hardness of the alloy was determined by Vickers hardness indentation. The measured coefficient of thermal expansion of the alloy exhibited an increase from 8.6—9.7*10^–6/K as temperature varied from ambient to 1000 K.

Th-30Zr合金的热力学性能

文献研究揭示了关于 Th-Zr 系统的数据匮乏。对Th-30Zr合金及其合成、显微组织和表征进行了研究。使用 X 射线衍射、光学显微镜和 SEM-EDS 对 Th-30Zr 合金进行了表征。对Th-30Zr合金的弹性性能进行了测量，结果表明，锆合金化提高了弹性模量。合金的硬度由维氏硬度压痕确定。随着温度从环境温度变化到 1000 K ，合金的热膨胀系数测量值从 8.6-9.7*10 ^{–6 /K 增加。}
