There are provided methods and systems for creating multi-phase covetics. For example, there is provided a process for making a composite material. The process includes forming a multi-phase covetic. The forming includes heating a melt including a metal in a molten state and a carbon source to a first temperature threshold to form metal-carbon bonds. The forming further includes subsequently heating the melt to a second temperature threshold, the second temperature threshold being greater than the first temperature threshold. The second temperature threshold is a temperature at or above which ordered multi-phase covetics form in the melt.
