A shear band (or, more generally, a 'strain localization') is a narrow zone of intense shearing strain, usually of plastic nature, developing during severe deformation of ductile materials. As an example, a soil (overconsolidated silty-clay) specimen is shown in Fig. 1, after an axialsymmetric compression test. Initially the sample was cylindrical in shape and, since symmetry was tried to be preserved during the test, the cylindrical shape was maintained for a while during the test and the deformation was homogeneous, but at extreme loading two X-shaped shear bands had formed and the subsequent deformation was strongly localized (see also the sketch on the right of Fig. 1).

The invention relates to the field of metal material preparation, in particular to a method for improving the indoor temperature compressing plasticity of an amorphous alloy. The method aims at solving the technical problem that due to the fact that an extremely localized shear band of an existing bulk amorphous alloy is fast expanded, a material fails and cracks. The method comprises the steps of1 assembling and 2 smelting. The technical method for manufacturing an amorphous alloy composite is simple, materials are wide and easy to obtain, the brittleness problem for large-scale industrialized application of the amorphous alloy can be solved well, and large industrialized application prospects are achieved. The method is used for preparing the amorphous alloy with good indoor temperaturecompressing plasticity.
