Materials that are strong and ductile are always favored and highly demanded by industry. However strength and ductility are usually anti-correlated in materials and are difficult to achieve simultaneously. While monolithic nanocrystalline metals and amorphous metallic glasses both exhibit higher strength as compared to conventional metals and alloys, their brittle natures severely limit their application as engineering materials.

高强度和韧性的材料一直受到工业界的青睐和高度要求。然而，强度和延展性通常在材料中是反相关的，并且难以同时实现。虽然单块纳米晶金属和非晶金属玻璃都表现出比常规金属和合金更高的强度，但它们的脆性性质严重限制了它们作为工程材料的应用。
