Description
- The present application claims priority to Chinese Patent Application No.
200710187786.2, filed November 30, 2007 - The present disclosure relates to a Zr-based amorphous alloy and a preparing method thereof.
- Amorphous metallic alloys are disordered in the long range but ordered in the short range. They have desirable physical and chemical properties, such as high strength, high hardness, high wearing resistance, high corrosion resistance, relatively wide elastic range, high electric resistance, good superconductivity, and low magnetic loss. Amorphous metallic alloys have huge potential when used as structural materials. They are widely used in many fields such as mechanics, IT electronics, the military industry and so on.
- However, some characteristics of the amorphous metallic alloys limit their applications. For example, it is difficult to manufacture large size amorphous alloys. To obtain the disordered structure in the long range, atoms' spontaneous movement in the freezing process shall be restrained. The higher the cooling speed is, the lower the possibility is for the atoms to form orderly arrayed crystalline materials via spontaneous movement. But as product size increases, the internal cooling speed within the product is declining. Thus, the internal amorphous degree is low in the long range and it is difficult to form large size amorphous structures.
- Also, it is difficult to effectively improve the plasticity characteristics of the amorphous materials. Due to their particular structure, while under stress, the amorphous alloy materials do not have the internal deformation mechanism as crystalline materials do in order to resist deformation. So when the stress reaches a certain degree, the amorphous alloy material may break suddenly, which may lead to catastrophic accidents. Thus, the applications of the amorphous alloy materials as structural materials are limited.
- Zhao et al. discloses a Zr-Ti-Cu-Ni-Be-Fe bulk amorphous alloy and its preparing method (Forming And Performance of The Zr-Ti-Cu-Ni-Be-Fe Bulk Amorphous Alloy And Amorphous-Based Nano-Composite, Zhao De Qian, Zhang Yong, Pan Ming Xiang, Meng Li Qin , Wang Wei Hua, Acta Metallurgica Sinica, March, 2000). The method comprises adding 2-10 atomic percent of Fe to form a nano crystalline composite material in order to change the magnetic susceptibility of the material. As a result of the addition of Fe in increasing amount, sharp diffraction peaks begin to appear in the XRD diagram, indicating crystallization. It shows that the addition of relatively large amount of iron is effective in affecting the amorphous alloy forming ability. Zhao et al. however does not address the issues of large size amorphous alloy manufacturing and the plasticity of the amorphous alloy materials.
- In one aspect, a Zr-based amorphous alloy comprises Zr, Ti, Cu, Ni, Fe, Be, and Sn.
- In another aspect, a Zr-based amorphous alloy comprises about 30-75 atomic percent of (ZrxTiySnz), about 10-35 atomic percent of (CumNin), about 0.1-15 atomic percent of Fe, and about 0.1-35 atomic percent of Be. Reference numerals x, y and z are atomic fractions, and x+y+z equals to 1, wherein x is about 0.6-0.85, and z is in the range of about 0.01x - O.lx. Reference numerals m and n are atomic fractions, and m+n equals to 1, and wherein m is about 0.5-0.65.
- In yet another aspect, a method for preparing a Zr-based amorphous alloy comprises melting a raw material comprising Zr, Ti, Cu, Ni, Fe, Be, and Sn to form an alloy mixture; and molding the alloy mixture to form the amorphous alloy.
-
Fig. 1 is the quasi-three component phase diagram (Zr, Ti, Sn)-(Cu, Ni)-(Be, Fe) of the amorphous alloy. -
