| 摘要 |
The present invention relates to an amorphous metal base composite allowing process hardening. The amorphous metal base composite includes a continuous amorphous metal base and a metastable second phase precipitated by polymorphic transformation in the base. The second phase is stably transformed by stress applied to a material during a deformation process to release the stress applied to the material, thereby preventing brittleness of the amorphous metal base from being damaged. The amorphous metal base composite includes: 35-60 atoms% of Ti, 35-50 atoms% of Cu, and 5-15 atoms% of Ni. The composite further includes at least one selected from a group consisting of Zr, Sn, Si, and Nb having a content of 3-15 atoms%. The present invention provides a composite material having a structure precipitated by the polymorphic transformation of the metastable second phase representing stress-induced phase change behavior. In the amorphous metal base composite material having the metastable second phase precipitated through the amorphous-polymorphic transformation in accordance to the present invention, the tolerance of the amorphous material is greatly improved due to the stress-distributed behavior by the stress-induced phase change of the second chamber such that the process hardening effect is made. |
