Abstract
Joined connections between a metallic compact body made by melting metallurgy and a body made by powder metallurgy are prepared by providing a pre-formed, unsintered pressed body having at least one component which forms a liquid phase at the sintering temperature, placing the pre-formed body directly in contact with a metallic compact body without application of external pressure and subjecting the contacted bodies to a temperature sufficient to sinter the pressed body but below the liquidus temperature of the compact body.
