EFFECT OF PROLONGED HEATING ON THE MECHANICAL PROPERTIES OF SINTERED ALUMINUM POWDER,
Abstract
Mechanical properties of sintered aluminum powder SAP-1 sheets produced by rolled lamination and of SAP-1 and SAP-3 rods that are pressed are studied in connection with the effect of prolonged heating; heating at 250 degrees C for 1000 and 5000 hours results in no influence on properties in short-term elongation. Sensitivity to cracking in impact bending is slightly reduced. Heating of SAP-1 sheets to a temperature above 450 degrees decreases ultimate strength at 20 degrees and increases relative elongation. At 250-500 degrees the strength characteristics undergo no change. Prolonged heating (100-5000 hours) at 250-500 degrees C has no effect on any grades of pressed SAP semifinished products.
