||The scope is to provide an opportunity of sharing recent technology advances in the science and technologies of lightweight metals, aluminum, magnesium and titanium alloys as well as other lightweight metallic materials including high entropy alloys and metal matrix composites. New theories and technologies on lightweight metallic materials are constantly being developed. It is generally a slow process to publish these findings in scientific journals. Therefore, it is essential for researchers to get the latest information in a timely manner. This annual conference attracts materials scientists and engineers from all over the world and provides a venue for technology dissemination.
