Abstract
The present invention relates to aero-manufacturing technology field, specifically provide a kind of structure property homogenization heat treatment method of the steel of laser deposition molding A 100, the high temperature anneal is carried out to it after the shaping of the steel of laser deposition molding A 100 first, it is heated in the range of 1100 DEG C~1300 DEG C and continues 2h~4h, room temperature is furnace-cooled to afterwards；Then after the completion of high annealing, 3 circulation normalized treatments are carried out to the steel of A 100, the normalized treatment includes the steel is heated into 900 DEG C ± 15 DEG C and continues 1h, and room temperature is air-cooled to afterwards；This method can eliminate the component segregation that laser direct deposition shapes the Steel materials of A 100, control tissue performance uniformity, it is ensured that the laser direct deposition shaping steel of A 100 can obtain good combination property.
Description
Technical field
The present invention relates to aero-manufacturing technology field, the structure property of more particularly to laser deposition molding A-100 steel is uniform
Change heat treatment method.
Background technology
Laser direct deposition shapes the one kind for belonging to increases material manufacturing technology, and A-100 steels are shaped using laser direct deposition
Make undercarriage pioneering for the world.A-100 steel is High-alloy Ultra-high Strength Steel, and alloying level is high, causes in laser direct deposition
Segregation phenomena easily occurs for material structure in shaping process of setting, is unfavorable for the uniformity of material structure performance, influences the comprehensive of material
Performance is closed, therefore how to control laser direct deposition to shape A-100 structure of steel performance uniformities, the component segregation of material is eliminated,
It is to ensure that laser direct deposition shaping A-100 steel can obtain good combination property and realize the key of application.
It is domestic at present still effectively to control laser direct deposition to shape A-100 structure of steel performance uniformities without a kind of
Method.
The content of the invention
To overcome at least one defect that above-mentioned prior art is present, the invention provides a kind of laser deposition molding A-
The structure property homogenization heat treatment method of 100 steel, comprises the following steps：
Step one, the high temperature anneal is carried out to it after the shaping of laser deposition molding A-100 steel, is heated to 1100
DEG C~1300 DEG C in the range of and continue 2h~4h, room temperature is furnace-cooled to afterwards；
After the completion of step 2, high annealing, 3 circulation normalized treatments, the normalized treatment bag are carried out to the A-100 steel
Include and the steel is heated to 900 DEG C ± 15 DEG C and continues 1h, room temperature is air-cooled to afterwards.
It is preferred that, the heating-up temperature of step one high temperature annealing is 1200 DEG C.
It is preferred that, the heat time of step one high temperature annealing is 2.5h.
It is preferred that, the heating-up temperature of normalized treatment is 900 DEG C in step 2.
The structure property homogenization heat treatment method for the laser deposition molding A-100 steel that the present invention is provided, can be eliminated sharp
Light Direct precipitation shapes the component segregation of A-100 Steel materials, controls tissue performance uniformity, it is ensured that laser direct deposition shapes
A-100 steel can obtain good combination property.
