a way to obtain semi-finished products of biphase titanium alloys

摘要

1.a way to obtain semi-finished products of biphase titanium alloys comprising heating in u03b2 - field deformation and cooling, and the fact that, in order to enhance the the strength and plasticity, as well as the fit, the temperature of heating in the area are u03b2 extract for 2 to 6 hours.the deformation of the conduct to the degree of 60% to 95% in the process of cooling to a temperature below the temperature of 150 to 250u00b0u0441 polymorphous transformations, and after cooling are u0446u0438u043au043bu0438u0447 u0435u0441u043au0443u044e processing by heating to a temperature below the temperature of 100 180u00b0u0441 polymorphous transformations extracts in 0.2 - 2 hours at this temperature.deformation with a degree of 20% to 50% in the process of cooling to a temperature below the temperature of 200 300u00b0u0441 polymorphous conversion and subsequent cooling to room temperature. u0440u0430u0442u0443u0440u044b, and in the last round of the conduct with a degree of 2 to 10% in the process of cooling to a temperature below the temperature of 150 to 180u00b0u0441 polymorphous u043fu0440u0435u0432u0440u0430u0449u0435u043du0438u044f.2. method for p.1, a fact that the heating in the u03b2 - area are at a temperature above the temperature of 150 250u00b0u0441 polymorphous u043fu0440u0435u0432u0440u0430u0449u0435u043du0438u044f.3. method for 1, which was, however, that in the last cycle of the cyclic heat treatment lead to the temperature at the temperature below 100 130u00b0u0441 polymorphous transformations and u0432u044bu0434 u0435u0440u0436u043au0443 is 0.2 - 1 hr.
