采用搅拌混合和超声处理技术相结合，生产出一种新型铝-玄武岩金属基复合材料。对基体-纤维界面的研究揭示了 Al-Si-Ca 和 Al-Fe-Si-Mn 金属间化合物 (IMC) 的形成，两相均呈现多面体形态。新复合材料的拉伸强度为 189MPa，比整体铝合金提高了 13%。尽管弯曲模量和弹性模量保持不变，但屈服强度提高了 22%，耐磨性提高了 33%。建议这些 IMC 有助于将载荷从基体转移到纤维。
A novel aluminium-basalt metal matrix composite has been produced by employing a combination of stir mixing and ultrasonication processing techniques. A study of the matrix-fibre interface has revealed the formation of Al-Si-Ca and Al-Fe-Si-Mn intermetallic compounds (IMC) with both phases displaying a polyhedral morphology. The new composite exhibited a tensile strength of 189 MPa, resulting in a 13% improvement over the monolithic Al alloy. A 22% increase in yield strength and a 33% increase in wear resistance were also achieved, although the flexural and elastic moduli remained unchanged. It is proposed that these IMCs assist in load transfer from the matrix to the fibres.
