Explosive compaction of CuCr alloys
摘要
The production of CuCr alloys utilizing explosive compaction was studied. Mixture powders of CuCr alloys placed in tubes with a dimension of d14.0 mm×21.4 mm can be compacted using explosive pads of 16.5 mm or 22.5 mm. Thicker pads of explosive make the compacts more porous. The effects of the ratio of m e/m p, ratio of m e/(m p+m t) and impact energy on the density of compacts were similar, they were chosen to control explosive compaction, respectively. When adequate value of the parameters m e/m p, m e/(m t+m p) and impact energy of unit area of tube was chosen, high density(7.858 g/cm 3), high hardness(HB189) and low conductance (13.6 MS/m) of CuCr alloys could be made by explosive compaction. The general properties of CuCr alloys by explosive compaction are similar to those of CuCr alloys by traditional process.
