Large plasticity and tensile necking of Zr-based bulk-metallic-glass-matrix composites synthesized by the Bridgman solidification J. W. Qiao,1 S. Wang,1 Y. Zhang,1,a P. K. Liaw,2 and G. L. Chen1 1State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, People’s Republic of China 2Department of Materials Science and Engineering, University of Tennessee, Knoxville, Tennessee 37996-2200, USA Received 2 March 2009; accepted 23 March 2009; published online 14 April 2009 The microstructures of the in situ bulk-metallic-glass-matrix composites are usually controlled by changing the alloy compositions. In this paper, Zr-based bulk-metallic-glass-matrix composites containing dendrites with a fixed composition of Zr37.5Ti32.2Nb7.2Cu6.1Be17.0 are synthesized by the Bridgman solidification. The sizes and volume fractions of dendrites in the composites are controlled by adjusting the withdrawal velocities. A linear relationship between the spanning lengths of individual dendrites and the withdrawal velocities is established. Large plasticity and tensile necking can be obtained by only controlling the cooling condition. © 2009 American Institute of Physics.
