本项目拟将某燃机TC17合金二级轮盘锻件的组织均匀性问题与探伤杂波底波

This project intends to combine the uniformity of the structure of a gas turbine TC17 alloy secondary wheel forging with the detection clutter and bottom wave loss. Based on the test and data accumulation, the forging structure and the detection of clutter and bottom wave loss will be preliminarily grasped. The relationship exists between the raw materials, the control of the intermediate billet structure, the optimization of the intermediate billet size structure, the adjustment of the deformation rate and the billet heating temperature to control the product forming process, and gradually improve the product structure to achieve uniform forging structure and non-destructive detection of clutter. The purpose of wave loss reduction.

In this project, it is proposed to combine the microstructure uniformity of TC17 alloy secondary wheel disc forging of a gas turbine with the flaw detection clutter and bottom wave loss, preliminarily master the relationship between forging microstructure and flaw detection clutter and bottom wave loss through test and data accumulation, and optimize the size and structure of intermediate blank by tightening the control of raw materials and intermediate blank structure, Adjust the deformation rate and blank heating temperature to control the product forming process, gradually improve the product structure, and achieve the purpose of uniform forging structure and reducing the clutter and bottom wave loss of nondestructive testing.<br>

In this project, the organization uniformity of TC17 alloy secondary disk forgings of a gas turbine is combined with the loss of flaw detection clutter, and the relationship between forging organization and flaw detection clutter and bottom wave loss is preliminarily grasped through experiments and data accumulation. By tightening raw materials and intermediate billet organization control, optimizing intermediate billet size structure, adjusting deformation rate and billet heating temperature, the product forming process is regulated and controlled, and the product organization is gradually improved, so as to achieve the purpose of uniform forging organization and lower noise bottom wave loss in nondestructive testing.
