Embodiment Construction
[0034] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] The embodiment of the present invention provides a TC4ELI titanium alloy for ultrasonic scalpel, which contains AL: 5.5-6.5%, V: 3.5-4.5%, Fe: 0.15-0.25%, Si: 0.1-0.5% by weight percentage %, O: 0.08-0.13%, C: 0-0.05%, N: 0-0.03%, H: 0-0.005%, and the rest are inevitable impurity elements in Ti and titanium sponge; the sum of the contents of the above components is 100%. Adding a small amount of Si element can improve the high temperature performance and creep resistance of the alloy.
[0036] Preferably, by weight percentage, containing AL: 6.12%, V: 4.01%, Fe: 0.17%, Si: 0.12%, O: 0.10%, C: 0.027%, N: 0.005%, H: 0.0017%, and the rest It is an inevitable i...
