A method is disclosed for producing a brake element, in particular a brake disk or brake drum, which has a friction portion and a fastening portion, wherein a blank for at least the friction portion is produced by a casting method from gray cast iron with lamellar graphite, wherein the blank is subjected to austenitizing at a predefined austenitizing temperature, and wherein the austenitized blank is subjected to austempering at a predefined austempering temperature. The friction portion and the fastening portion is produced in one piece, and that the fastening portion is produced with a wall thickness of at least 1.5 and at most 4.5 mm.

A method of austempering of steel parts is described. The steel parts are initially austenitized and subsequently quenched to a start temperature which is higher than the martensite start temperature. Then the steel parts are subjected to a first isothermal holding at the start temperature for a first time period. Subsequently the steel parts are held for a second isothermal time period at a finish temperature which is higher than the start temperature. The method described is particularly well suited for rapid austempering of steel parts, a pure bainitic structure being achievable, and the core hardness of the steel parts obtained being settable via the start temperature, the finish temperature, the duration of the first time period, and the duration of the second time period.
