摘要：
An aluminum magnesium alloy with reduced Samson phase at grain boundaries made from the method of providing aluminum in a container, adding boron to the container, providing an inert atmosphere, arc-melting the aluminum and the boron, and mixing the aluminum and the boron in the container to form an alloy mixture. A method of suppressing the Samson phase, Al3Mg2, at grain boundaries in Aluminum, comprising providing aluminum in a container, adding boron to the container, providing an inert atmosphere, arc-melting the aluminum and the boron, and mixing the aluminum and the boron in the container to form an alloy mixture.
