Abstract: In this work, HCP-to-FCC phase transformation and its interaction with {112¯2} compression twins (CTWs) in CP-Ti under ultra-high-strain-rate compression (∼106/s) was investigated. Muti-scale characterization and analysis demonstrate the both B- and P-type FCCTi lamellae are profusely generated and exhibit significant growth capability and intensive interaction with the CTWs. Particularly, two adjacent FCCTi lamellae with a twinning relationship can be formed within the CTW and matrix, respectively. Moreover, two adjacent FCCTi lamellae with nearly identical orientation can be formed within the two different CTW variants. Two possible mechanisms were proposed to account for this unique phenomenon.
