再结晶织构的建模:商用铝和镍合金中立方体带形核的量化

基本信息

项目摘要

The aim of this project is development of recrystallization model for texture and microstructure prediction in commercial Al and Ni alloys. The formation of cube texture in Al sheets and in high temperature super conductors is very much of concern due to strong influence on material properties. The adaptive cellular automat CORe is used for simulation of the recrystallization process. This model was developed during SFB 370 project and allows direct coupling to hardening-, precipitation- and texture models. Thereby, also nucleation processes can be investigated. The focus of this work is the improvement of the cube texture prediction. Special in-situ investigations of the nucleation on cube bands by means of EBSD technique and TEM are essential. Based on experimental results (incubation time, influence of microchemistry, substructure evolution, nucleus number per band etc.) the CORe model should be improved to be able to give the right prediction of recrystallization texture and especially of cube orientation. Experimental investigations should be carried out on commercial Al and Ni-W alloys.
本项目的目的是发展再结晶模型,用于预测工业铝和镍合金的织构和显微组织。铝片和高温超导体中立方织构的形成对材料性能有很大的影响,因而备受关注。采用自适应元胞自动机CORe对再结晶过程进行模拟。该模型是在SFB 370项目期间开发的,可以直接耦合到硬化,沉淀和纹理模型。因此,也可以研究成核过程。本文工作的重点是立方体纹理预测的改进。利用电子背散射衍射技术和透射电子显微镜对立方带形核过程进行原位研究是十分必要的。根据实验结果(孵化时间、微观化学的影响、亚结构演化、每条带的核数等),应改进CORe模型,以便能够正确预测再结晶织构,特别是立方取向。应在工业Al和Ni-W合金上进行实验研究。
