Abstract:

Bright ghost defect were found on products which made of TA15 titanium alloy bar when macroscopic

test. The microstructure is observed, by which the abnormal area for TA15 is principally determined . The chemical

compositions of that area is charactered by SEM,and the microhardness is tested by microhardness tester. The results

show that the titanium content in the segregation is higher than that in the normal area, the aluminum content in the

segregation is lower than that in the normal area, and the Vickers hardness in the segregation area is lower than that in

the normal area, that is so called non鄄brittle segregation metallurgical defect . For the material of TA15 with segrega鄄

tion structure, when the properties is according with the standard, the bar can be delivered as long as cut鄄off the seg鄄

ment with segregation.

Key words:TA15 titanium alloy, Bright ghost defect,Non鄄brittle segregation
