Embodiment 1

[0034] A certain GH4133 forging was found to be bulging and cracked after blanking-blank chamfering-heating-upsetting. The location and shape of the defect are as follows: figure 1 shown by figure 1 It can be seen that the crack defect cracks along the axial direction of the forging, and one end of the crack is rounded (near the lower end face), and the other end is sharp (near the upper end face). The deepest crack is about 10mm. The internal fracture surface of the crack is divided into two parts. One part is close to the bottom of the crack, and the fracture surface is irregularly torn; the other part is close to the surface of the forging, and the fracture surface is relatively flat, basically perpendicular to the surface.

[0035] A kind of GH4133 alloy forging defect detection method, such as Figure 7 As shown, the specific steps are as follows:

[0036] Step 1. Macro organization analysis;

[0037] Step 2, microstructure analysis;

[0038] Step 3, microstructure c...

Abstract

The invention discloses a defect detection method for GH4133 alloy forgings. The defect detection method is specifically implemented according to the following steps of 1, macroscopic structure analysis, 2, microscopic structure analysis, and 3, microscopic structure component analysis. According to the method, for the cracking problem generated in the production process of the GH4133 forging, the cracking reason of the forging can be analyzed through methods such as low-magnification inspection, high-magnification inspection and energy spectrum analysis, and the analysis process is systematic and complete.

Description

technical field [0001] The invention belongs to the technical field of metallurgical defect analysis and relates to a method for detecting defects of GH4133 alloy forgings. Background technique [0002] GH4133 alloy has good comprehensive properties and is suitable for manufacturing turbine disks and working blades of aero-engines. GH4133 forgings are prone to cracking problems during the production process. There are many reasons for the problems. There are many detection methods used to analyze the causes of cracking problems in the laboratory but they are not systematic. Therefore, the laboratory needs a systematic analysis method at present. The cause of the cracking problem, the present invention can analyze the cracking problem of the GH4133 forging in the production process through low-magnification inspection, high-magnification inspection and energy spectrum analysis and other methods to analyze the reason for the cracking of the forging.
