提出了严重塑性变形(SPD)的一个新的研究方向，我们称之为SPD诱导的杂化材料合成。它的核心是创造出内部结构，这种结构是由固体中的各种材料制成的。与传统的金属成形不同，SPD诱导合成在不改变固体外部几何形状的情况下产生了工程设计的内部结构。论证了SPD技术在材料合成方面的可能性。这一新兴领域的研究将为制造先进的混合材料开辟新的途径，同时也提出了一些具有挑战性的科学问题。讨论的一个特殊应用涉及具有增强结构延展性的混合超细晶材料的开发。
An emerging direction of research into severe plastic deformation (SPD), which we refer to as SPD-induced synthesis of hybrid materials, is presented. At its core is the creation of inner structure made from various materials within the bulk of a solid. As distinct from the traditional metal forming, SPD-induced synthesis produces an engineered inner architecture of the solid without changing its exterior geometry. The possibilities of the SPD techniques with regard to materials synthesis are demonstrated. Research in this nascent area will open up new avenues for fabrication of advanced hybrid materials, while also posing a number of challenging scientific problems. A particular application discussed concerns the development of hybrid ultrafine-grained materials with enhanced structural ductility.
