Abstract

The use of rapid electrocontact heating (by an electric current) in quenching dispersion-hardening alloys opens new prospects for substantial improvement of their properties by providing the requisite degree of dissolution of the excess phases with retention of the fine-grained structure of the supersaturated solid solution, which is difficult to attain under the conditions of conventional heating. The advantage of such quenching is connected with the possibility of short-term superheating of the alloy above the temperature of heating for quenching conventionally used. Therefore, such a treatment is expedient foremost for alloys that contain poorly soluble excess phases. The present work concerns the role of the heating rate for quenching in formation of the phase composition and structure of quenched dispersion-hardening spring alloy 36NKhTYuM8.
