Abstract
Continual annealing and roll-bonding (CAR) process was used in this study as a very effective method for fabrication of the Al/15 vol.% SiO2 metal matrix composite. The microstructure of the produced composites after 6 cycles of the CAR process was showed an excellent distribution of SiO2 particles in the AA1100 matrix without any porosity. Particle breaking was one of the most important phenomena that can occur in CAR process. The results also were indicated that when the number of CAR cycle was increased, the tensile strength of the manufactured composites was improved, but their elongation was decreased at first step and then was increased. The tensile strength of the composite was 1.77 and 1.63 times higher than the same values was obtained for annealed and monolithic aluminum strips, respectively, while the elongation value was decreased slightly.
期刊介绍：
Materials Science and Engineering A provides an international medium for the publication of theoretical and experimental studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. Appropriate submissions to Materials Science and Engineering A should include scientific and/or engineering factors which affect the microstructure - strength relationships of materials and report the changes to mechanical behavior.
