Effect of Concentrate Location on Acoustic Emission Severity Estimation for TC4 Titanium Alloy Ring Pressure Vessels

According to analyzing acoustic emission data of TC4 Titanium Alloy Ring Pressure Vessels, combined with the structural characteristics and types of location, the effect of concentrate location on acoustic emission severity estimation was addressed and the way to distinguish concentrate location level was summarized. The paper brings some examples to show that the flexible application of correlative verification is needed while estimating acoustic emission severity according to the level of concentrate location.
