研究了添加碳元素对大块非晶合金热稳定性和硬度的影响。结果表明，少量碳的加入进一步扩大了合金的过冷液范围，提高了合金的热稳定性和强度。添加更多的碳会形成晶态和非晶态的混合物，并伴随着显微硬度的显著增加。从结构角度讨论了碳的添加对非晶态合金的影响。
The effects of carbon addition on thermal stability and hardness of Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous alloy were investigated. It is found that a small amount of carbon addition further extends the supercooled liquid range and enhances the thermal stability and strength of the alloy. More carbon addition results in the formation of a crystalline and amorphous mixture accompanied by a pronounced increase in microhardness. The effects of the carbon addition on the amorphous alloy are discussed from the structural point of view.
