Introduction As the improving of material science and engineering, the mechanical properties of aluminum alloys become to better and better.
The aluminum alloys have been taken an important part of the building materials.
The multi-phase aluminum alloys are the most popular engineering materials[1], where one phase acts as the matrix and the others serve as the reinforcing elements.

It is also a kind of important biological material.
Due to the increasing demand of whiskers, especially for reinforcing biomaterials, there has been considerable research on development of easy and cost-effective synthetic methods for preparing whiskers which have good biocompatibility. 2 Experiments The starting materials are commercially available.
The picture shows, the shape of the crystal is neat, so preparation of crystal material by molten salt method can get its good growth under the low temperature.
