Magnesium-lithium alloy has become the most important lightweight alloy material in the world for its outstanding strength, stiffness and excellent processing properties. The study on phase transition mechanism of magnesium-lithium alloy can be used to guide the composition design and preparation of magnesium-lithium alloy. But lithium atoms are difficult to observe by most methods, which hinders the study of distribution of lithium atom in magnesium-lithium alloy and its influence on phase transition of magnesium-lithium alloy. Neutron diffraction is a useful method to analyze lithium atoms and provides a useful way to study the atomic structure and phase transformation mechanism of magnesium-lithium alloy. In this work, neutron diffraction is used to analyze magnesium-lithium alloy, the atomic structures of magnesium-lithium alloy with different phases are obtained by pair distribution function method(PDF), and the atomic diffusion behavior and phase transition mechanism of magnesium-lithium alloy are studied based on the atomic structures.
