Effect of copper and nickel coating on short steel fiber reinforcement on microstructure and mechanical properties of aluminium matrix composites

“…Combining these observations with the tensile test results, it can be concluded that the brittle intermetallic phase preferentially cracks prior to significant plastic flow of the matrix or reinforcing phase. Baron et al [8] have reported that steel preform reinforced composites show failure that occurs within the interfacial intermetallic phase. This crack might have initiated at the pore or from the intermetallic compound between the fibers and the aluminium.…”

“…Baron et al [8] investigated two types of sintered metal preforms (steel and stainless steel) reinforced aluminium composites prepared by varying squeeze casting conditions. It was observed that a detrimental reaction phase containing iron, aluminium and silicon was formed around the metallic particles.…”

Effect of wt% reinforcement on microstructure and mechanical properties of Al–2Mg base short steel fiber composites

“…The cracks are propagated along the fiber/matrix interface within the reaction phase that cause failure of the material. Baron et al (1997) have reported that steel preform reinforced composites show failure to occur within the interfacial intermetallic phase. It is evident from the fractographs (Fig.…”

Investigation of Al/Steel Bimetal Composite Fabrication by Vacuum Assisted Solid Mould Investment Casting

“…However metalmetal composites have not been studied as much as metalceramic composites, metallic reinforcements have great potential with providing cost advantage compared to ceramic reinforcements [3].…”

“…Baron et al [3] investigated two types of sintered metal preforms (steel and stainless steel) reinforced aluminium composites prepared by varying squeeze casting conditions. Also Colin et al [5] used stainless steel bre preforms for aluminium matrix composite production with squeeze casting.…”
