However, at the same time as its ultrahigh strength, the BMG in the plane stress state has almost no inelastic behavior at room temperature
This makes its failure form sudden failure

Abstract

This invention relates to the method for producing plastification geode / massive metal glass composite material. The steps are: first, selecting alloy components having strong glass formation ability, regulating the components to make them offset eutectic point, and solid solution phase being separated earlier; second, the components being smelted under shield gas, then producing foundry alloy ingot; then, said ingots being broken, resmelted, subjected to low pressure casting / water-cooling copper mould quick cooling formation to produce branch like crystal / massive metal glass composite material sheet, finally, said sheet being subjected to isothermal treatment and then water-quenching to produce this invented product. The plastificiation beta phase is no longer having branch like shape but having ball shape.

Description

a technical field [0001] The invention relates to a preparation technology of a metallic glass composite material, in particular to a method for spheroidizing dendrites in a bulk metallic glass composite material. Two background technology [0002] Bulk metallic glass (BMG) has a series of excellent properties different from crystalline alloys, and has been involved in five major engineering applications, including military products, electronic product casings, medical devices, sports and leisure products, and space engineering materials. In particular, it has 3 to 4 times the strength of the corresponding crystalline alloy, making it very attractive in terms of weight reduction of weaponry. However, in parallel with its ultrahigh strength, BMGs in the plane stress state show little inelastic behavior at room temperature. This makes its failure form a sudden failure. [0003] In order to solve this problem, after introducing the crystalline phase on the BMG matrix, a cryst...
