Third Partial Report on the Thermal Behavior and Mechanical Properties of Iron-Manganese and Iron-Manganese-Nickel Alloys
Abstract
Alloys which contain 3-4 per cent Mn, 1-1 1/4 per cent Ni, 1/4 per cent Mo, have excellent ductility. When heat treated to simulate the cooling conditions at the center of an air cooled 18 inch plate, the alloys gave fibrous fracture in both the coupon and high velocity shock tests, which indicate that these alloys may have useful ballistic properties in heavy sections. A low temperature impact study of an alloy MDS showed that it was ductile down to temperatures of -90 degree C (-130 degree F). The mechanical properties are superior to those required for heavy forgings under Navy Specifications 49S2 for Class An steel.
