摘要: The mechanical behaviour of fully amorphous and partially crystallized Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass (BMG) was studied in the supercooled liquid region. In experimental domain, Newtonian flow can be obtained state but as strain rate is increased, a transition from to non-Newtonian detected. After primary crystallization, apparent viscosity significantly increased deformability composite residual / nanocrystals still large. However, such conditions, behaviours are promoted.
