The existence of defects in titanium forgings may affect the processing quality or processing quality of the subsequent processes, and some seriously affect the performance and use of the forgings, and even greatly reduce the service life of the finished parts and endanger safety. Therefore, in order to ensure or improve the quality of forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of forging defects, necessary quality inspections should also be carried out to prevent subsequent processes (such as heat treatment, surface treatment, cold working) And forgings with defects that have adverse effects on performance flow into subsequent processes. After quality inspection, remedial measures can be taken on the forgings made according to the nature of the defect and the degree of influence to use, so that it meets the technical standards or requirements for use.
Therefore, in a sense, the quality inspection of forgings, on the one hand, is to check the quality of the forgings that have been made, and on the other hand, to point out the direction of improvement for the forging process, so as to ensure that the quality of forgings meets the requirements of forging technical standards and meets the design, Requirements on processing and use. The inspection of forging quality includes the inspection of appearance quality and internal quality. Appearance quality inspection mainly refers to the inspection of the geometric size, shape, surface condition and other items of the forging; the internal quality inspection mainly refers to the inspection of various items such as the chemical composition, macrostructure, microstructure and mechanical properties of the forging.
