    The composition of nickel and molybdenum containing partially prealloyed steel powders was optimised for the production of ultrahigh strength sintered components via compaction, sintering, and heat treatment. A Fe-l Mo-2Ni powder attained a maximum tensile strength of 1920MN m-2 when double pressed, double sintered, and heat treated. Single pressed, single sintered, and case hardened compacts made from the same powder showed strengths of 1500MN m-2 which is greater than the maximum tensile strength (1300 MN m-2) of existing high strength sintered materials. The sintered compacts remained relatively soft before heat treatment, allowing machining and sizing. The strengthening is attributed to the strain induced martensitic transformation of nickel rich austenite. PM/0553.
