Patent GB-720252-A (GB)
Title: Improvements relating to the heat treatment of steel
Filed: 1952-12-18
Abstract: Steel is heat treated by heating to form austenite, cooling to a temperature below the Ms point but above the Mf point to transform a portion only of the austenite, reheating to a temperature above the Ms point to temper the martensite formed and then cooling to below the Mf point.  The amount of austenite converted to martensite by the first cooling may be between 25 and 95 per cent.  The time of tempering the first martensite should not be long enough to allow an appreciable quantity of the residual austenite to transform to bainite, e.g. not more than 2 minutes.  The finished steel may be tempered at a temperature below the first tempering temperature.  The cooling after the first tempering may be to a sub-zero temperature.
