ScholarBank@NUS Repository. https://doi.org/10.1016/j.actamat.2004.05.025 | Abstract: | A systematic study has been carried out to identify the effect of crystalline second phase reinforcements on the mechanical properties of amorphous alloys based on the composition La86-yAl14(Cu, Ni)y (y = 1-24). By varying the composition in a controlled manner, composites with a tailorable fraction of in situ dendritic reinforcements were produced. Tension, compression and impact tests showed considerably improved mechanical properties with a large amount of plasticity when the reinforcement volume fraction exceeded a critical value near 40%, and the tension/compression asymmetry associated with glass plasticity is reduced as the volume fraction of crystalline reinforcements rises. © 2004 Acta Materialia Inc.
