分形理论在材料显微组织定量化分析中的应用
首发时间:2013-01-07
摘要:材料显微组织演变过程中微观组织的复杂性、多变性和非规则性,为定量化研究材料工艺、组织和性能之间的关系带来了巨大的挑战。分形理论的提出为非规则变形组织的定量化研究提供了一种新的方法。利用分形维数描述显微组织的基本参数,可解决组织测量参数量化这一难题,并建立起材料性能-金相组织-分形维数之间的关系模型。该方法已被广泛应用于材料科学的许多领域,在金属断裂、合金凝固与相变、材料磨损、薄膜研究和材料的微结构等方面都取得了很大的进展。本文总结和分析国内外关于分形理论在材料显微组织定量化研究中的应用进展,有利于进一步认识材料微观组织演变并建立材料组织与性能之间的量化关系。

Applications of fractal theory for the quantitative analysis of microstructure in materials
Abstract:Due to the complexity, variability and irregularity of microstructure during the microstructure evolution in materials, it caused a big challenge for establishing the relationship between the microstructures and their properties. Fractal theory was provided as a new method for quantitative analysis of irregular microstructures. The fractal dimension was carried out to describe the microstructural parameters, which can solve the quantification of microstructures, and established the relationship among property, microstructure and fractal dimensions. This method has been widely used in many fields, such as metal fracture, solidification, phase transformation, wear of metal and film, etc. This paper summarizes and analyzes the progress of fractal theory for quantitative study the microstructure in China and abroad. It is helpful to further understanding the microstructure evolution and establishing the quantitative relationship between microstructure and properties.
Keywords: Non-ferrous metal and alloy Fractal theory Quantification Microstructure Titanium alloys
