TEM Study of Precipitates in Melt‐Spun Mg‐Zn‐Y‐La Alloys

Abstract

Recently, nano‐crystalline MgZn 1 Y 2 alloys exhibiting excellent tensile yield strength elongation ratio have been developed as a consequence of preliminary investigations of alloy compositions using melt‐spun ribbons. Their results show that the novel long‐period hexagonal atomic configurations in the Mg‐Ln‐Zn alloys as well as the atomic scale enrichment of Ln and Zn elements into the misfit atomic array sites indicates the possibility that a high‐strength Mg‐based alloy is developed by the control of the novel structure and the atomic scale segregation mode.
