Abstract

A new concept of solidification method by compression shearing is developed. By this method the grain size of the fabricated material is fined to nanometer scale, and the strength of the specimen is improved. Appling compression shearing process to powder Aluminum under room temperature and in the atmosphere, we can obtain a thin plate specimen consist of ultra fine crystal grains with preferred orientation. By following conventional ways, it was not possible to obtain such specimen under room temperature. In this paper, we described the structural and mechanical properties of fabricated specimen with 100-200nm crystal grain size, which is obtained by Compression Shearing Method.
