%J 金属学报 %D 2009 %I %X Plastic Zr58.5Ti14.3Nb5.2Cu6.1Ni4.9Be11.0 bulk metallic glass matrix composites containing uniformly distributed dendrites in the glass matrix were synthesized by the Bridgman solidification methold. Through tailoring the withdrawal velocity, the volume fraction of dendrites with characteristic spanning length, as well as the mechanical properties of the samples can change. The characteristic spanning length of the individual dendrites roughly obeys linear relationship with the withdrawal velocity. The compressive ultimate strength and the fracture strain of the sample reached 1930 MPa and 11.3%, respectively, when the withdrawal velocity was 1.0 mm/s. %K Zr--based bulk metallic glass %K composite %K unidirectional solidification %K mechanical property
