THE EFFECT OF COLD DEFORMATION ON THE PROPERTIES AND STRUCTURE OF SHEETS OF SINTERED ALUMINUM POWER (SAP),

Abstract

Sintered aluminu, powder SAP material is considerably strengthened in cold deformation by cold hardening of the aluminum matrix. Material relaxation with simultaneous increase in plastic properties results from heating to a temperature above 600 degrees C. Recrystallization through process annealing is observed after exposure of 0.5-1.0 h; with an increase in exposure time, material properties barely change. High-temperature annealing (650 degrees C) sharply increases tensile characteristics at elevated temperatures. After exposure of more than 1.0 h polygonization begins in the material and structure changes.
