采用差示扫描量热法（DSC）、差热分析法（DTA）、X射线衍射法（XRD）和压缩试验研究了一系列Ti 40 Zr 10 Cu 40 − xPd 10 +x（x=0、2、4、6、8、10）块体非晶合金的热性能、非晶形成能力（GFA）和力学性能。该系列大块非晶合金由于不含Ni、Al、Be等有毒元素，有望用作生物医用材料。Ti40 Zr 10 Cu 36 Pd 14合金具有最大的非晶形成面积（GFA），最大直径为6 mm，并且具有很高的热稳定性，过冷液相区（ΔTx）为49 K。与传统的生物医用钛合金相比，该块体非晶合金具有更高的比强度（2.7× 105 Nm/kg）和更低的杨氏模量（82 GPa）。这有利于在生物材料中的应用。
The thermal properties, glass forming ability (GFA) and mechanical properties of a series of Ti40Zr10Cu40−xPd10+x(x=0, 2, 4, 6, 8, 10) bulk glassy alloys were examined by differential scanning calorimetry (DSC), differential thermal analysis (DTA), X-ray diffractometry (XRD) and compressive test. The series of bulk glassy alloys are expected to be used as biomedical materials because of the absence of toxic elements such as Ni, Al and Be. The Ti40Zr10Cu36Pd14alloy exhibits the highest GFA, resulting in a maximum diameter of 6mm, and high thermal stability with a supercooled liquid region (ΔTx) of 49K. The bulk glassy alloy has higher specific strength of 2.7×105Nm/kg and lower Young's modulus of 82GPa than those of conventional biomedical Ti alloys. These are favorable for application to biomaterials.
