然而，目前国内外所用的铜合金材料一直都存在着高强和高导之间的矛盾，如何在保持高的导电性的前提下，有效地提高其力学性能已经成为铜合金材料研究和发展的中心任务，因此寻找一种兼顾高强度与高导电

On the other hand, if Ti foil is too thick, the interfacial reaction between liquid Cu-Ti alloy and Al〓O〓 ceramic can proceed sufficiently, due to the widening of the liquid phase region. This results in a too thick reaction layer, which also reduces the joint strength. Further more, in this situation, not all of the liquid alloy is isothermally solidified, similar to the case of brazing, the heatresistant of joint can't be improved.

相反，Ti箔过厚，一方面由于液相区宽度增大，连接过程中始终为Cu-Ti液体合金与陶瓷反应，导致形成过厚的反应层，降低接头强度；另一方而，由于连接后液相区未能完全等温凝固，与活性钎焊相类似，接头耐热性也难以得到提高。

Results showed that at a given position on the storage vessel surface, the hoop strain was increased with a higher packing fraction of alloy powders during the cyclic hydriding/dehydriding reactions. This resulted from a larger amount of pulverized fine powders generated by a larger packing fraction of alloy powders.

结果显示，在储氢罐表面之特定位置上，其切线方向应变随著粉末填充率提高而增加，这是由於较高的粉末填充率产生较多的粉碎细小粉末所导致。
