titanium master alloy

It can be used to weld the refractory metal and metal that difficult to weld, such as titanium alloy, aluminum alloy, etc. In addition, laser welding process has no pollution to the environment and the technology is easy to master.

它能够焊接难熔、难焊的金属，如钛合金、铝合金等。此外，激光焊接过程对环境没有污染，技术简便。

When the titanium content is lower, the grain refinement effect of Al-Ti-B master alloy is slightly superior to that of electrolytic low-titanium aluminum alloys. But when the titanium content is higher, they have almost same grain-refining ability.

钛含量较低时，熔配加Al-Ti-B中间合金的细化效果略好于电解加钛，当钛含量较高时，二者的细化能力基本相当。

The results show that the titanium added by electrolysis has better effect of grain refinement than that of the titanium added by the master alloy.

结果表明，电解掺钛具有更优良的晶粒细化作用。
