Abstract

Recent research in the material science field is focused on the easy-to-apply and cost-effective production of the structural components with enhanced mechanical properties. As an answer to these new trends in the present study, the inexpensive household aluminum foils are used to produce the multilayer aluminum matrix composite. The aluminum matrix composites are manufactured by hot-rolling of the sandwiched foils and afterward subjected to microstructural characterization and mechanical testing. Analysis of the produced composite microstructure and fracture surface obtained after tensile testing was performed using the scanning electron microscopy (SEM). The qualitative fractographic analysis revealed that the ductile fracture features prevail in the overall fracture mode of the investigated multilayer composite, while the quantitative fractographic investigation allowed more detailed insight into the composite failure process and depicted critical parameters that led to the composite failure.

Summary

Introduction

Modern research trends in the field of material science and especially in the field of metallic materials for structural applications are focused on the innovative, costeffective production solutions for the obtainment of structural materials with enhanced mechanical properties. Metal matrix multilayer composites are singled out as materials that offer enhanced mechanical, thermal, electrical, and magnetic properties suitable for numerous structural applications [1,2]. 349-355 are required [3] Due to their low density and good corrosion resistance, the aluminum alloys are considered good candidates as a matrix material in the modern metal matrix composites perceived for aeronautical, automotive, and military applications [3,4,5,6]
