Thermal expansion of aluminum matrix composites reinforced by carbon nanotubes with in-situ and ex-situ designed interfaces ceramics layers

In this study we aim at examining the effect of in-situ and ex-situ interfacial ceramic layers at the Al-CNT interface on the thermal expansion coefficient of aluminum matrix composites at different temperatures. For this, two types of bulk composite materials were obtained by a combination of high-energy ball milling and hot pressing methods. These materials were based on the aluminum alloy reinforced with CNT with in-situ Al4C3 and ex-situ TiC...
