Abstract

Aluminium alloys suffer from a serious backlash of low formability, hindering their implementation in the automobile sector, where demand has been skyrocketing for decades. However, warm forming techniques have been reported to bear the ability to curb this problem using a forming temperature below the recrystallization point, owing to the direct contribution of the activated non-octahedral slip systems. This calls for an investigation on the onset of secondary slip systems along with an estimation of microstructural characterization and analysis of crystallographic texture since both are expected to have a staggering influence on the mechanical properties at elevated temperatures. Hence, the present investigation deals with thorough microstructural analysis derived from the Electron Back Scattered Diffraction (EBSD) maps and analysis of crystallographic texture through Orientation Distribution Function maps of EN AW 6061 samples deformed through tension both at room and elevated temperature (250 °C). Furthermore, Visco Plastic Self Consistent (VPSC) modelling along with the Finite element (FE) method has also been incorporated with an aim to verify the crystallographic texture and deformation behaviour, respectively. These extensive characterization methodologies provided compelling evidences of the formation of deformation substructures at elevated tempaerature along with distinct represtation of work hardening behaviour of the material. The texture analysis further elaborated on the influence of high temperature on the reduction of unidirectional defects at high temperature, allowing it to regain its symmetry.

非八面体滑移面在6061铝合金自然时效拉伸变形行为中的作用研究
铝合金因成形性低而受到严重抵制,阻碍了其在汽车行业的应用,而汽车行业的需求几十年来一直在飙升。然而,据报道,由于活化的非八面体滑移系统的直接贡献,热成形技术能够通过低于再结晶点的成形温度来抑制这一问题。这就要求对二次滑移系统的开始进行研究,同时对微观结构特征进行估计,并对晶体结构进行分析,因为这两者都有望对高温下的机械性能产生惊人的影响。因此,本研究通过电子背散射衍射(EBSD)图和取向分布函数图对室温和高温(250°C)拉伸变形的EN aw6061样品进行了全面的显微结构分析和晶体织构分析。此外,Visco塑性自洽(VPSC)建模以及有限元(FE)方法也被纳入其中,目的是分别验证晶体结构和变形行为。这些广泛的表征方法提供了令人信服的证据,证明在高温下变形子结构的形成,以及材料加工硬化行为的独特表现。织构分析进一步阐述了高温对高温下单向缺陷减少的影响,使其恢复对称性。图形抽象

期刊介绍: Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
