摘要

研究了基于冷剧烈塑性变形的复杂铝合金热机械加工过程中两级（基体和第二相）纳米结构的现象学和性质。通过控制第二相的参数，在加工的各个阶段都考虑到结构非均质性优化原则的重要性。本文提出了一些结论，这些结论可作为该原则的准则基础，适用于涉及严重塑性变形的合金处理，以确保其有效的纳米结构和性能增强。提出了一种纳米合金分类的新方法。

Nanostructuring, Structure Heterogeneity, and Static Strength of Complex Aluminum Alloys

The phenomenology and nature of two-level (matrix and second phases) nanostructuring of complex aluminum alloys during thermomechanical processing based on cold severe plastic deformation are considered. The importance of taking into account the principle of structure heterogeneity optimization at all stages of processing by controlling the parameters of second phases is substantiated. A number of conclusions are formulated that can be used as the basis for the criteria of this principle for the alloy treatment involving severe plastic deformation to ensure its effective nanostructuring and property enhancement. A new approach to classification of nanostructured alloys is proposed.
