Size effects (SEs) exist in many domains, and are caused by changes in the values of parameters of materials, structures, or systems individually or collectively known as size effect factors. SEs induce a variety of scale-dependent behaviours, phenomena, and performances during the multiscale processing and manufacturing of materials, such as the macro-, meso-, and microscale ones examined by the researches described in this paper. Furthermore, the parts and components fabricated from multiscale processing and manufacturing exhibit the scatters of quality and properties. This paper uses multiscale machining and deformation-based manufacturing as the case studies of material processing and manufacturing to review and analyse SEs and their manifestations. The current status of multiscale manufacturing research and its possible future avenues are articulated and discussed, and key problems that must be solved and unknowns that must be understood are highlighted. This paper thus presents a broad understanding and insight into SEs that influence the material processing and manufacturing for making multiscale parts and components. It also examines the bottleneck problems generated by SEs in such processing and manufacturing arena, and how these can be solved to enable the high efficiencies of multi-scale materials processing and manufacturing to be realised.

多尺度材料加工制造中的尺寸效应

尺寸效应 (SE) 存在于许多领域,是由材料、结构或系统的参数值的变化单独或统称为尺寸效应因子引起的。在材料的多尺度加工和制造过程中,SEs 会引发各种与尺度相关的行为、现象和性能,例如本文中描述的研究检查的宏观、中观和微观尺度。此外,通过多尺度加工和制造制造的零件和组件表现出质量和性能的分散性。本文以多尺度加工和基于变形的制造作为材料加工制造的案例研究,回顾和分析 SE 及其表现形式。阐述和讨论了多尺度制造研究的现状及其未来可能的途径,并强调了必须解决的关键问题和必须理解的未知数。因此,本文对影响制造多尺度零部件的材料加工和制造的 SE 提供了广泛的理解和洞察。它还研究了SE在此类加工制造领域产生的瓶颈问题,以及如何解决这些问题以实现多尺度材料加工和制造的高效率。因此,本文对影响制造多尺度零部件的材料加工和制造的 SE 提供了广泛的理解和洞察。它还研究了SE在此类加工制造领域产生的瓶颈问题,以及如何解决这些问题以实现多尺度材料加工和制造的高效率。因此,本文对影响制造多尺度零部件的材料加工和制造的 SE 提供了广泛的理解和洞察。它还研究了SE在此类加工制造领域产生的瓶颈问题,以及如何解决这些问题以实现多尺度材料加工和制造的高效率。
