强塑性变形（SPD）是将传统的粗晶金属和合金转变为超细晶（UFG）材料的一种方法。超细纤维材料具有许多改善的机械和物理性能，这使得它们具有广泛的商业用途。然而，任何将SPD技术用于商业的尝试都需要更好地了解SPD工艺的机制和实用性。本文探讨了SPD工艺的历史发展，并侧重于SPD等方面的材料流，静水压力的作用，摩擦，工具的几何形状，坯料和进料的考虑，技术可行性等这些主题的讨论设置的背景下决定进一步研究和SPD的商业化。
Severe plastic deformation (SPD) is used to convert traditional coarse grain metals and alloys into ultrafine-grained (UFG) materials. UFG materials possess a number of improved mechanical and physical properties which destine them for a wide commercial use. However, any attempt to use SPD technology commercially requires a better insight into the mechanics and practicality of SPD processes. This paper looks into historical development of SPD processes and focuses on such aspects of SPD as material flow, role of hydrostatic pressure, friction, geometry of tools, billet and feeding considerations, technical feasibility, etc. The discussion of these topics sets a background for decisions concerning further research and commercialisation of SPD.
