摘要：

A YB12 strengthening precipitate of 9 nm is reported for the first time in a Mg-7 wt.% Y alloy after high-pressure bonding processing. The formation of nanoscale YB12 particles with a high melting point improves the strength of the Mg-Y alloy significantly and this is coupled with its thermal stability. In addition, the age-hardening response is weakened because of the decrease in yttrium supersaturation in the Mg matrix. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
