| 摘 要： | 目的：研究及比较Ｔｉ－７５金属在牙科铸造后的机械性能。方法：利用Ｉｎｓｔｒｏｎ拉伸试验机，对Ｔｉ－７５金属牙科铸造后部分力学性能进行了测试研究，并与Ｔｉ－６Ａｌ－４Ｖ及临床常用钴铬合金进行了比较。结果：Ｔｉ－７５铸造后抗拉强度为８５６．７ＭＰａ，屈服强度为５４０ＭＰａ延伸率为７．３％。Ｔｉ－６Ａｌ－４Ｖ铸造后抗拉强度为９５６．７ＭＰａ，屈服强度为５９０ＭＰａ，延伸率为５．２％。Ｃｏ－Ｃｒ合金铸造后抗拉强度为６５１．２ＭＰａ，屈服强度为４７８．８ＭＰａ，延伸率为６．１％。结论：Ｔｉ－７５金属铸造后抗拉强度，屈服强度及延伸率等性能指标均优于钴铬合金，延伸率也高于Ｔｉ－６Ａｌ－４Ｖ合金。

| Abstract: | Objective: To study the mechanical properties of Ti 75 alloy after casting. Methods: The mechanical properties of Ti 75 alloy were tested with dynamometer(Instron) and compared with that of Ti 6AI 4V and cobalt chromium alloy. Results: After casting the tensil strength of Ti 75 alloy was 856.7MPa, elastic limit 540MPa and elongation 7.3%. The tensil strength of Ti 6Al 4V alloy was 956.7MPa, elastic limit 590MPa and elongation 5.2%. The tensil strength of Co Cralloy was 651.2MPa, elastic limit 478.8MPa and elongation was 6.1%. Conclusion: Ti 75 alloy shows higher strength and greater elongation than Co Cr alloy in tensile tests, lower strength and greater elongation than Ti 6Al 4V alloy after casting. |
