Metallic plastics based on misch metals

We report a family of metallic plastics (MPs) based on misch metals with extremely low glass transition temperature Tg, similar to that of typical polymers such as polyvinyl chloride. In near boiling water, these MPs show superplasticity and can be shaped and imprinted with complex micro- or nano-patterns. Such materials with much low cost compared with that of the MPs based on pure rare-earth metals make them closer to applications. The work might also stimulate more researches for finding new polymerlike metallic alloys.
