With the rapid development of science and technology and industrial production, people have higher and higher requirements for the quality of mechanical parts. Although the quality of materials and the precision of parts have been greatly improved, the early failure of mechanical parts used in various industries still occurs from time to time. Through failure analysis, it is essential to find out the failure causes and put forward effective improvement measures to prevent the recurrence of similar failure accidents, so as to ensure the safe operation of the project.

The failure form of metal is closely related to the failure cause. The failure form is the apparent feature of the metal failure process, which can be observed in an appropriate way. Through metal failure analysis, we can know whether there are problems in the performance of metal materials or metal equipment in advance, so as to avoid possible accident hazards in engineering application.

Metal failure analysis method

Metal failure analysis process

The metal failure analysis process is as follows:

1. Collect background information

2. Sampling test

3. Analysis and discussion

4. Prepare metal failure analysis report

Failure of metal components may have very serious results, so failure analysis should be done. It is to analyze the causes of metal failure, speculate the possibility of failure, and give reasonable explanations and solutions. Some do not pay attention to failure analysis, but as a subject that has not developed for a long time, the role of failure analysis is huge.
