Abstract
The invention discloses an aging treatment method of a high-temperature alloy GH2328 material. The aging treatment method comprises the following steps: carrying out primary aging treatment: insulating heat of a GH2328 material part subjected to solution for 10 hours at the temperature of 750 DEG C, and then carrying out air cooling; and carrying out secondary supplement aging treatment: insulating heat of the part subjected to the primary aging treatment for 5 hours at the temperature of 650+/-10 DEG C, and then carrying out air cooling, thus obtaining the high-temperature alloy GH2328 material. According to the aging treatment method disclosed by the invention, the GH2328 material part subjected to solution is obtained by washing the GH2328 material part with gasoline, putting the washed part in a common electric furnace so as to be subjected to solution for 45 minutes at the temperature of 1160+/-10 DEG C and then carrying out water cooling. By using the aging treatment method disclosed by the invention, the hardness of the high-temperature alloy GH2328 material can be improved.
Description
Technical field
The present invention relates to the heat treatment technics field, relate in particular to a kind of aging treatment method of superalloy GH2328 material.
Background technology
Superalloy all adopts solution treatment usually, makes the alloying element solid solution go into matrix, gives full play to the solution strengthening effect, if again through ageing treatment, can make carbide or metallic compound deposition be disperse and distribute the effect of performance precipitation strength and grain-boundary strengthening.The alloy that has can adopt secondary solid solution or middle ageing treatment, to obtain suitable grain size, makes carbide or metallic compound more favourable in quantity, size and distribution.And the GH2328 material belongs to nickel base superalloy, and this material contains more nickel, chromium element, for the aging technique of this material, does not see relevant report.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and a kind of aging treatment method that can improve superalloy GH2328 material hardness is provided.
The aging treatment method of a kind of superalloy GH2328 material of the present invention may further comprise the steps:
(1) ageing treatment for the first time: with the GH2328 material parts of solid solution at 750 ℃ of insulation 10h, air cooling;
(2) replenish ageing treatment for the second time: the part that will pass through the ageing treatment first time is at 650 ± 10 ℃ of insulation 5h, and air cooling promptly gets.
The aging treatment method of above-mentioned superalloy GH2328 material; Wherein: the GH2328 material parts of solid solution is with gasoline the GH2328 material parts to be cleaned up; Then cleaned part is put into common electric furnace, at 1160 ± 10 ℃ of solid solution 45min, water-cooled promptly gets.
The present invention compared with prior art; Have following tangible advantage and useful effect; Can know from above technical scheme: material is after solid solution; Through 750 ± 10 ℃ of timeliness; Can obtain bigger strengthening effect (hardness value is about 53HRC); Carry out 650 ± 10 ℃ of additional timeliness second time again, help eliminating stress and improve the distribution of strengthening phase, can further improve the strength of materials and hardness (hardness value is about more than the 57HRC).This shows that present method is passed through the selection of progressive aging temperature and soaking time, thereby has improved the strength of materials and hardness.
The specific embodiment of the present invention further specifies beneficial effect of the present invention.
