The Strength of Sintered Powder Artefacts

JSGT 1947 V31 T270-T273

The tensile strength of pressed powder artefacts, measured at room temperature, increases as the temperature, at which they are heated, is raised. When the “sintering” temperature is expressed as a percentage of the absolute melting point temperature, the strength versus sintering temperature curves of powder artefacts with widely differing melting points are found to be very similar. These experimental results suggest a physical interpretation of the sintering process which may have a more general significance.
