Introduction TC4 alloy is a type of α+β titanium alloy, it owes comprehensive mechanical properties, high strength and good thermal processing characteristics.
Forged TC4 alloy leads to the unevenness of forging organization due to the deformation, leading to the unevenness of the organization being heat-treated and the unevenness of properties distribution.
Therefore control the uniformity of TC4 organization can control the uniformity of properties of parts to reduce post-processing deformation.
The system can avoid some human factors, it operates smoothly, its probe positions accurately , it owes high efficiency, it achieves automatic ultrasonic testing and saves labor costs.
However, because there are many factors that will affect the propagation velocity of ultrasonic waves.
