for 3 hours the breaking elongation of tensile test rods made from the slices was 3 1 at 1100 u00b0 c and the breaking stress was 117 4 kg mm 2 the same result was obtained when the powder instead of being extrusion pressed was consolidated in a hot isostatic press at 1050 u00b0 c for 1 hour at a pressure of 3000 bars were mechanically alloyed under argon in a netzsch co s 1 attritor for 40 hours and thereby cold worked the total amount of combined powder was 1000 grams the volume ratio of steel balls powder was 1 9 the powder was drawn off into soft iron capsules and the capsules were welded shut the encapsulated powder was heated to 1100 u00b0 c and extrusion pressed in the reduction ratio 20 1 cylindrical slices 40 mm high were taken from the extrusion product and compressed to 10 mm in thickness in a forging die at a temperature of 700 u00b0 to 800 u00b0 c and a pressure of about 60 kg mm 2 then the slices were subjected to a coarse grain annealing at 1275 u00b0 c for three hours the breaking elongation of tensile test rods made from the slices was 5 at 1100 u00b0 c and the breaking stress was 50 2 kg mm 2 the same result was obtained when the powder instead of being extrusion pressed was consolidated by hot isostatic pressing at 1050 u00b0 c for 1 hour at a pressure of 3000 bars were mechanically.
