Porous copper has gained significant attention in numerous structural and functional applications like heat exchanger, heat pumps, rechargeable batteries, fuel cells, EMI absorbers, purification of water etc., due to its several attractive properties. Fabrication of porous copper with monomodal pore distribution via powder metallurgy technique using different space holders like K₂CO₃, NaCl, etc. and investigation of different properties have been carried out systematically and extensively. However, fabrication of porous copper with bimodal pore distribution using powder metallurgy technique and investigation of its different properties is still lacking. In the present investigation, porous copper with bimodal pore distributions have been fabricated via powder metallurgy technique using mixture of K₂CO₃+NaCl as space holder. The particle size of the NaCl powders used was considerably larger than the K₂CO₃ particles and correspondingly, the pore structure of the bimodal samples consisted of both large pores and fine network pores. Presence of NaCl as space holder in the bimodal samples results in improved bonding between the Cu particles, thereby enhancing the compressive strength and stiffness compared to the monomodal samples, for similar content of space holder particles. For bimodal samples, energy absorbed until densification was found to be monotonically increasing, with increasing amount of porosity. Whereas, in case of the monomodal samples, the energy absorbed increased up to a critical porosity and then decreases. The different pore morphology distribution also has certain influence on the densification behaviour during compression. While the stiffness increases for the bimodal samples after densification, for the monomodal samples the pores play a vital role in reducing the stiffness after densification.
