Method of producing sintered ferrous materials
Abstract
Abstract THE USES OF SINTERED FERROUS MATERIALS FOR IMPORTANT STRUCTURAL MACHINE PARTS ARE CONSIDERABLY LIMITED BECAUSE OF SUBSTANTIALLY INFERIOR MECHANICAL PROPERTIES IN USUAL FORGINGS AND CASTINGS OF THE SAME COMPOSITION IN SPITE OF THE FACT THAT SINTERING MATERIALS CAN BE PRODUCED AT RELATIVELY LOW COST AND THEY ELIMINATE MACHINING DUE TO THE CLOSE TOLERANCES OBTAINABLE. IN ORDER TO OVERCOME THE ABOVE-MENTIONED FAULTS AND TO ATTAIN SINTERED FERROUS MATERIALS WITH HIGH DENSITY, HIGH STRENGTH AND EXCELLENT DUCTILITY, THERE IS PROVIDED A METHOD OF LIQUID PHASE SINTERING OF FERROUS MATERIALS IN WHICH FE-SI ALLOY POWDERS WITH MORE THAN 7 WEIGHT PERCENT OF SI, AND THE REMAINDER FE ARE ADDED TO IRON POWDERS AT THE RATE OF 0.3-10 WEIGHT PERCENT OF SI.
