摘要
Mg-8at%Y-4at%Zn alloy is processed via a conventional casting method. The TEM images show the long-period ordered structure with six layered atomic packing in the matrix region of the cast ingot. High elastic modulus and hardness are attained due to the long-period ordered structure as a result of indentation tests. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
