中科院合肥物质科学研究院了解到，该院固体所研究团队近日在国内率先成功制备出同时具有高强度、高热稳定性的高界面铜钽（Cu/Ta）纳米多层膜块体材料。这项成果突破了传统纳米材料高温条件下的不稳定性问题，为下一代核电装置结构材料的设计提供了思路。
纳米结构材料，因为其高强度及丰富的界面被认为是下一代核电装置的理想候选材料。然而，传统的纳米结构材料在高温、强辐照等极端条件下结构和性能都不稳定。固体所内耗与固体缺陷研究室核材料研究团队以大塑性变形法，有效克服了材料在累积叠轧过程中出现的塑性不稳定现象及边裂问题。力学性能测试结果表明，其强度达到了初始原材料的5倍。更为重要的是，这种材料还具有非常优异的高温热稳定性。
