Powder Metallurgy of Non-Ferrous Metals: Part I

The Rules of Ferrous Metallurgy

The ways in which the sciences have been delineated and categorized throughout history provide insights into the formation, stabilization, and establishment of scientific systems of knowledge. The Dresdener school’s approach for explaining and categorizing the genesis of the engineering disciplines is still valid, but needs to be complemented by further-reaching methodological and theoretical r...

Sintering Aids in Powder Metallurgy THE ROLE OF THE PLATINUM METALS IN THE ACTIVATED SINTERING OF REFRACTORY METALS

When a metallic powder is subjected to a suffkiently high pressure a certain amount of adhesion takes place between individual particles. If this compact i s then sintered the bond is improved by diflusion and intergranular grain growth. The earliest known platinum objects were fabricated by such a powder metallurgical process, and when European scientists first addressed the problem of manufac...

Analysis of total metals in waste molding and core sands from ferrous and non-ferrous foundries.

Waste molding and core sands from the foundry industry are successfully being used around the world in geotechnical and soil-related applications. Although waste foundry sands (WFSs) are generally not hazardous in nature, relevant data is currently not available in Argentina. This study aimed to quantify metals in waste molding and core sands from foundries using a variety of metal-binder combi...
