制约非晶合金大规模商业应用的关键问题除了尺寸之外,最重要的是其表现出的室温脆性。为了解决这个问题,需要深入探索非晶合金的塑性变形机制,实现金属玻璃的韧脆转变。由于非晶态物质是复杂的多体相互作用体系,具有长程无序原子结构和独特的物理和力学性质,探索非晶固体是否存在类似晶体的缺陷,如何发现、表征以及建立非晶中流变单元与其性能、性质和特征的关系仍然是凝聚态物理和材料科学的难题。 Key Issues Restricting Large-Scale Commercial Applications of Amorphous Alloys In addition to size, the most important is the room temperature brittleness it exhibits. In order to solve this problem, it is necessary to explore in depth the plastic deformation mechanism of amorphous alloys and realize the ductile-to-brittle transition of metallic glass. As amorphous materials are complex multi-body interaction systems, with long-range disordered atomic structure and unique physical and mechanical properties, to explore whether amorphous solid-like defects exist, how to find, characterize, and the establishment of amorphous rheological units Its relationship with its properties, properties and characteristics remains a difficult issue for condensed matter physics and material science.
