A research team headed by Prof. Wang Weihua from the Key Laboratory of Extreme Conditions Physics of the CAS Institute of Physics has developed a new kind of cerium-based bulk metallic glasses with an exceptionally low glass transition temperature, similar to or lower than that of many polymers. CAS scientists demonstrate that, in near-boiling water, these materials can be repeatedly shaped, and can thus be regarded as metallic plastics. Their resistance to crystallization permits extended forming times above the temperature and ensures an adequate lifetime at room temperature.
