Abstract
The invention provides a thermal treatment technology for improving overall performance of a precipitation-hardening stainless steel turbine blade. The problems that a precipitation-hardening stainless steel material is insufficient in strength and insufficient in impact property in a thermal treatment process can be effectively solved. The thermal treatment technology is characterized by comprising the following steps: firstly, carrying out preheat treatment on a blade, and then carrying out thermal treatment on the blade according to a conventional thermal treatment technology, wherein the preheat treatment is to carry out one-time high-temperature solution treatment on the blade and then carry out one-time medium temperature adjustment on the blade.
Description
Technical field
The present invention relates to the thermal treatment process field of turbine blade, especially relate to the thermal treatment process field of PH Stainless Steel turbine blade, be specially a kind of thermal treatment process that improves PH Stainless Steel turbine blade over-all properties.
Background technology
The PH Stainless Steel such as 0Cr17Ni4Cu4Nb, X4CrNiCuMo14-5 and X5CrNiCuNb16-4 are owing to having high strength, excellent toughness and excellent corrosion resistance, thereby in turbine blade heavy forging field, have application more widely.The manufacture of turbine blade heavy forging is produced and is had relatively high expectations for the over-all properties of material, in the production process of PH Stainless Steel turbine blade, because yield strength and the defective thing of product rejection that causes of impelling strength of material happens occasionally.
Summary of the invention
For the problems referred to above, the invention provides a kind of thermal treatment process that improves PH Stainless Steel turbine blade over-all properties, it can effectively solve PH Stainless Steel material undercapacity, problem that impact property is inadequate in heat treatment process.
A kind of thermal treatment process that improves PH Stainless Steel turbine blade over-all properties, it is characterized in that: first blade is carried out to conditioning heat treatment, and then thermal treatment process is heat-treated described blade routinely, described conditioning heat treatment is processed for first described blade being carried out to a high temperature solid solution, then in carrying out once to described blade, temperature adjustment is processed.
It is characterized in that:
The processing requirement that described high temperature solid solution is processed is, described blade is evenly put in general quenching charging basket, more described quenching charging basket is put into quenching furnance is heated to 1020 ℃～1060 ℃, is incubated two hours, more air-cooled or air cooling;
The processing requirement that the adjustment of described middle temperature is processed is, described blade is evenly put in general quenching charging basket, more described quenching charging basket is put into quenching furnance is heated to 800 ℃～900 ℃, is incubated two hours, more air-cooled or air cooling.
The beneficial effect of thermal treatment process of the present invention is: by blade being carried out to conditioning heat treatment before conventional thermal treatment, that blade material is organized is more even for it, thereby improves the over-all properties of blade after thermal treatment.
