Using high frequency induction brazing and TiZrNiCu filler metal, the shear strengths of the joints were low. The maximum shear strengh was only 102.1MPa, which was lower than the maximum strength of vacuum brazing. The reasons may be that excessive intermetallics, holes and oxidation existed in the joint. So TiZrNiCu filler metal isn't fit for non-vacuum brazing.The stress variation, stress distribution and crack-sensitive regions during the cooling process of brazing have been studied by Marc non-linear software.

采用气体保护高频感应加热、TiZrNiCu钎料钎焊时，接头的强度普遍偏低，最高的剪切强度只有102.1MPa，远远低于辐射加热真空钎焊的强度，其原因是接头中局部生成了过量的金属间化合物，且产生氧化，接头中含有较多的气孔等影响了接头强度，因此可以认为TiZrNiCu钎料不适合在非真空条件下的钎焊。
