ABSTRACT:
A hole is formed in a high-strength steel part and a lubricant consisting essentially of one or more metal powders, preferably of nickel or molybdenum; a metal powder which is more reactive than the steel of the workpiece such as zinc; and an organic medium is applied. A forming mandrel having a generally cylindrical shape with a frustoconical portion on either end is centered over the hole. The mandrel is pushed through the hole at a rate such that the steel adjacent the hole is coldworked and its microstructure is transformed from an austenitic to a normal tempered martensitic structure.
