A Method to Identify Which Structure Will be Chosen in the Forming Process of an L21 Structure

Nowadays, the Heusler alloy is a hot material system explored for new functional materials in condensed matter physics and materials science. A lot of Heusler alloys usually have a cubic L 2 1 structure with high chemical ordering. The L 2 1 structure has two types: Cu 2 MnAl-type and Hg 2 CuTi-type...

Description
Summary:Nowadays, the Heusler alloy is a hot material system explored for new functional materials in condensed matter physics and materials science. A lot of Heusler alloys usually have a cubic L 2 1 structure with high chemical ordering. The L 2 1 structure has two types: Cu 2 MnAl-type and Hg 2 CuTi-type. For given elements, different L 2 1 structures can generate different properties. Based on the minimum energy theory, a method is proposed to determine which structure will be chosen from the two in the crystallization of an L 2 1 structure.
