Abstract

In-suit β-Ti(Zr,Nb) dendrite/amorphous matrix composites were prepared by copper injection casting, specimens (1.5:1 aspect ratio) with different diameters were tested under quasi-static compressive loading at different strain rate. The results show that the structure of amorphous composites is amorphous matrix and in-suit β dendritic crystal phase; for 3mm and 4mm specimens, with the change of strain rate, the compressive strength and the fracture strain have no obvious changes. however, positive strain rate sensitivity was observed to 5mm specimens; in the same strain rate, with the decrease of the diameters, compressive strength and fracture strain all have great increases, which indicate the amorphous composites has obvious size effect.
