Abstract
The invention relates to a monomer separation method for a harmful phase of an isothermal forging die material for a turbine disc. The method comprises the following steps that firstly, a mixed solution containing the harmful phase and multiple strengthening phases is electrolytically extracted from a sample of the isothermal forging die material for the turbine disc; a proper amount of glycerol is added into the mixed solution to adjust the viscosity after electrolysis is finished; and by using the density difference of the harmful phase and the strengthening phases and the sedimentation ratedifference of the harmful phase and the strengthening phases in a liquid with the specific viscosity, a solid harmful phase single-phase entity is independently separated out . The method solves theproblem that in the prior art, the harmful phase and the strengthening separation phases can be separated, only in a mixed state at the same time, from a matrix, but the monomer harmful phase cannot be separated out in a single-phase mode is solved, realizes the single-phase separation of the harmful phase of the isothermal forging die material for the turbine disc, and can be used for accurate quantitative analysis of the harmful phase.
Description
Technical field [0001] The present invention is a monomer-separation method such as a harmful phase such as an isoelectric forged mold material for a turbine disc, which is a technical field of high temperature structural materials. Background technique [0002] The high temperature alloy is a large number of hot-end components for the manufacture of aeroeirs, known as "the heart of the gas turbine". Nickel-based high-temperature alloys are also a key material for the manufacture of ship power and power generation gas turbines, carrier rocket engines, ultra-supercritical power plant units, chemical fields, marine engineering equipment and isothermal forging die. The turbine dish is an important core heat part of the aerospace engine. Its working conditions are extremely harsh, and the complex heat, mechanical load, and the stress and temperature it will be subjected to the stress and temperature of each part. Therefore, it is required to have sufficient mechanics of the turbine d...
