Summary

With the development of science and technology, diversified demands on material properties have emerged. Different from single metal materials, metal-based functional composite materials have the potential to integrate the excellent properties of various constituent materials, and have a “synergy effect” while keeping the properties of each constituent metal or alloy, which renders more optimal performance and unique functional advantages. As an innovatively structured functional composite material that can save resources and improve material performance, such materials meet the requirements of sustainable development and helps to achieve “carbon peak” and “carbon neutrality”, with broad application prospects.
