摘要：
Blow molding is introduced as a net-shape process for bulk metallic glass (BMG). The forming takes place in the supercooled liquid region, where the viscosity of the BMG permits forming pressures that can be created with the force exerted by the human lung alone. The absence of external friction during the initial stages of forming allows large forming tangential strains. A simple model suggests strains of up to 10,000% are achievable under suitable processing conditions. (c) 2007 Acta Materialia, Inc. Published by Elsevier Ltd. All rights reserved.
