Abstract:The experimental research was carried out on the ultrasonic characteristics of 3 kinds of TC18 titanium alloys,
which were manufactured by laser additive manufacturing, electron-beam additive manufacturing and forging, respectively.
The research reveals that, in contrast with forged titanium alloy, additive manufacturing titanium alloy has obvious
directivity, which is manifested in the difference in velocity, attenuation and ultrasonic sensitivity of different directions.
The results are of great value to the ultrasonic testing method research of additive manufacturing products.
