Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys

Rare Metals, EarlyView.
ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.

Discussion on Strain Accommodation Associated with Formation of LPSO Structure

MATERIALS TRANSACTIONS, 2013
Plate-shaped precipitates accompanying change of chemical composition/order exhibit characteristics of displacive transformation when stacking sequence changes. One of intrinsic nature of long-period stacking ordered (LPSO) structures is, regular arrangements of stacking faults should cause significant change in local elastic strain field.
