development of tib2 reinforced aluminum foundry alloy based in situ composites part i an improved Halide Salt route to fabricate al 5 wt tib2 master composite
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2014Co-Authors: Zongning Chen, Tongmin Wang, Yuanping Zheng, Yufei Zhao, Huijun KangAbstract:Abstract In Part I of the two part study, an improved Halide Salt route was developed to fabricate in situ TiB2 particulate reinforced aluminum matrix master composites based on the well-established flux assisted synthesis (FAS) method using mechanical stirring. By microstructural and element-recovery analysis, we show how the simple but effective “improved method” – leaving the reactant molten Salt on the surface of aluminum melt without introducing any stirring during holding – influences the mechanical performance of the final composites. Processing parameters in terms of holding duration, reaction temperature and stirring speed before casting were optimized to produce Al–5 wt% TiB2 composite with consistent and sound quality. The experimental Al–5TiB2 composite, prepared under the improved Halide Salt route condition, has achieved a 140% improvement in the UTS without compromising its ductility with respect to the Al matrix. The experimental validation of using the developed Al–5TiB2 composite as a master composite to reinforce aluminum foundry alloys will be presented in Part II.

development of tib2 reinforced aluminum foundry alloy based in situ composites part ii enhancing the practical aluminum foundry alloys using the improved al 5 wt tib2 master composite upon dilution
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2014Co-Authors: Tongmin Wang, Zongning Chen, Yuanping Zheng, Yufei Zhao, Huijun KangAbstract:Abstract This is Part II of the two part study. Part I we dedicated to optimization of the fabrication of in situ TiB2 particulate reinforced aluminum matrix composites. In this part, efforts were made to confirm the strengthening effects of the Al–5 wt% TiB2 composite, as a “master composite”, on the practical foundry alloys, i.e. AlSi7Mg0.3, AlCu4.5Si1.1 and AlZn6Mg0.5. Experimental work and theoretical analysis are presented to interpret the improved yield strength of the diluted composites as influenced by their microstructures. The theoretically predicted and fitted values were in good agreement with the observed microstructural features and particle distribution, strongly supporting the mechanisms we proposed. The remelting and diluting approach can achieve superior improvement in UTS with respect to the conventional Halide Salt route, while compromising less ductility of the final composite. This characteristic is attractive from both technological and economic standpoints. Technologically, the present work can assist in providing strengthening strategies for different aluminum foundry alloy systems.

grain refining potency of al b master alloy on pure aluminum
Scripta Materialia, 2011Co-Authors: T.m. Wang, Hongwang Fu, Ying Fu, Zongning Chen, Jun Xu, Tingju LiAbstract:Al–B master alloys were ascertained to be efficient grain refiners on pure aluminum. Without introducing any stirring during reaction, three experimental Al–3B master alloys were prepared via the Halide Salt route by varying the Salt addition temperature, i.e. 750, 850 and 950 °C. All of them showed grain refining potency on pure aluminum and that with the 950 °C addition temperature was found to be the most efficient. Resistance to fading was also noted during holding after inoculation with this master alloy.
