摘要
The "abc" deformation method for production of large-scale billets with submicrocrystalline structure was developed. A large billet of Ti-6Al-4V alloy (150-mm diameter x 200-mm length) with a homogeneous submicrocrystalline structure was produced. The refined structure with a grain/subgrain size of about 0.4 mum leads to a substantial mechanical properties improvement. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
