The effect of sublimable vehicle composition in the camphor-naphthalene system on the pore structure ofporous Cu-Ni alloy is investigated. The CuO-NiO mixed slurries with hypoeutectic, eutectic and hypereutectic compo-sitions are frozen into a mold at -25oC. Pores are generated by sublimation of the vehicles at room temperature. Afterhydrogen reduction at 300oC and sintering at 850oC for 1 h, the green body of CuO-NiO is completely converted toporous Cu-Ni alloy with various pore structures. The sintered samples show large pores which are aligned parallel to thesublimable vehicle growth direction. The pore size and porosity decrease with increase in powder content due to thedegree of powder rearrangement in slurry. In the hypoeutectic composition slurry, small pores with dendritic morphologyare observed in the sintered Cu-Ni, whereas the specimen of hypereutectic composition shows pore structure of plateshape. The change of pore structure is explained by growth behavior of primary camphor and naphthalene crystals dur-ing solidification of camphor-naphthalene alloys.
