基于 Zr 的体积金属性的玻璃(BMG ) composites 与在 situ,形成的 Y2O3 粒子加强被 ultrahigh-oxygen-containing 的 Y 的合适的增加综合形成眼镜的合金先锋。composites 的微观结构,热稳定性,和机械性质被调查。玻璃形成被 Y 增加极大地在合金提高,结果的粒子在玻璃质的矩阵是同质地分布式的,允许氧化物分散的制造加强了 BMG composites。分别地,压缩力量和坚硬与 Y2O3 粒子的介绍增加了 10% 和 20% 。这些结果与用在工业条件下面的商业高氧的内容原料的改进性质为基于 Zr 的 BMG 和 BMG composites 的设计和生产是重要的。
Zr-based bulk metallic glass (BMG) composites with in situ formed Y203 particle reinforcements were synthesized by proper additions of Y to ultrahigh-oxygen-containing glass-forming alloy precursors. Microstructures, thermal stabilities, and mechanical properties of the composites were investigated. Glass formation was greatly enhanced by Y additions in the alloys and the result- ant particles were homogenously distributed in the glassy matrix, allowing for the fabrication of oxide dispersion strengthened BMG composites. The compressive strength and hardness increased by 10% and 20%, respectively, with the introduction of Y203 particles. These results are significant for the design and production of Zr-based BMGs and BMG composites with improved properties using commercial high-oxygen content raw materials under industrial conditions.
