Problems encountered in UT of titanium alloy forgings

Prone defects in titanium alloy forgings

1.Segregated defect

2. Inclusions

3. Residual shrinkage

4. Holes

5.crack

6. Overheating

There are several issues that need attention in ultrasonic flaw detection of titanium alloy forgings.

1. Metallurgical quality of raw materials

2. Select the appropriate test method

3. Need to evaluate each acceptance standard

With the continuous promotion of the application of titanium alloys,
the metallurgical quality requirements of more and more important bearing parts replacing steel will be higher and higher,
especially the use of ultrasonic testing technology to control the metallurgical quality of titanium alloy forgings and the ultrasonic response
There is still a lot of in-depth work to be done on the relationship between the microstructure and mechanical properties of titanium alloys.
