摘      要：In the present work,a compressible and lubricating space-holder material commonly known as acrawax was used to process Cu foams with various pore sizes and various *** foams were processed without using binders to avoid contamination of their metal *** lubricant space-holder material was found to facilitate more uniform flow and distribution of metal powder around the surface of the space *** addition,the use of acrawax as a space-holder material yielded considerably dense cell walls,which are an essential prerequisite for better material *** foams processed with a smaller-sized space holder were found to exhibit better electrical and mechanical properties than those processed with a coarser-sized space *** isotropic pore shape,uniform pore distribution throughout the metal matrix,and uniform cell wall thickness were found to enhance the properties pertaining to fine-pore foam *** processed foams exhibit properties similar to those of the foams processed through the lost-carbonate sintering process.
