THE INCREASE IN THE STRENGTH OF PRESSED SEMIFINISHED SINTERED ALUMINUM POWDER (SAP) PRODUCTS,

Abstract

The properties of sintered aluminum powder semifinished products within a single grade are determined primarily by the temperature to which the powder is heated prior to briquetting. This temperature reaches an optimum between 680 and 700 degrees Centigrade since it provides for high tensile characteristics, high density and low gas content in conjunction with limited exposure time. An increase in exposure time permits reduction of the temperature range by 80 to 100 degrees. A 10-15 percent reduction in tensile characteristics results from annealing of the hot-pressed sintered aluminum powder briquettes, with a slight increase in relative elongation.
