Abstract
A new MIM in-process joining technique has been developed for more complicated and functional MIM components by application of exuded wax from green compacts during solvent debinding step. Same and different materials using various stainless steels and iron were combined, and the joining behaviors and properties were investigated by tensile test and microscopic observation. Perfect joining thin and hollow compacts were obtained for the combination of same and different stainless steels, whereas it was difficult to join the iron and stainless steel compacts in hydrogen atmosphere because of the different starting temperature of shrinkage. However, pretty good joined iron and stainless steel compacts were obtained by consideration of particle size and vacuum atmosphere. Finally, for she combination of ferro-silicon and austenitic stainless steel compacts, high functionality (magnetic (1.60Tesla) & non-magnetic) and perfect joint were obtained.
