Abstract The increase of B4C addition into an AA6061-B4C composite system will not be always an ideal choice for improved properties because of the issues related to incorporation, distribution, and interfacial wetting while stir-casting. In such a case, ultrasonication is considered to be an alternative to get the advantage of microstructural changes which in turn improve the properties. In the present study individual B4C distribution and the refinement of microstructure was achieved at 4wt.%B4C. The improved specific ultimate and compressive strengths at 4wt.%B4C were observed as 36.32% and 43.92% whereas specific Vicker’s and Brinell hardness as 53.41% and 50.89% respectively.2009 Elsevier Ltd.

通过新型超声辅助搅拌铸造开发的 AA6061-B4C 复合材料的机械性能增强

摘要 在 AA6061-B4C 复合体系中添加 B4C 并不总是改善性能的理想选择，因为搅拌浇铸时存在与掺入、分布和界面润湿相关的问题。在这种情况下，超声波处理被认为是获得微观结构变化优势的替代方法，从而改善了性能。在本研究中，单个 B4C 分布和微观结构的细化是在 4wt.%B4C 下实现的。在 4wt.%B4C 下观察到的比极限强度和压缩强度提高了 36.32% 和 43.92%，而比维氏和布氏硬度分别为 53.41% 和 50.89%。2009 Elsevier Ltd. 保留所有权利。
