Mechanical behavior of B4C particulate-reinforced 7091 aluminum composite

Studies to characterize the microstructure and mechanical properties of B4C particulate reinforced metal matrix composites using 7091 Al alloy matrix material are reported. Tensile and yield strength, and tensile modulus of the monolithic matrix alloy can be improved, but ductility and fracture toug...

Zusammenfassung:	Studies to characterize the microstructure and mechanical properties of B4C particulate reinforced metal matrix composites using 7091 Al alloy matrix material are reported. Tensile and yield strength, and tensile modulus of the monolithic matrix alloy can be improved, but ductility and fracture toughness need to be improved through optimization of processing parameters. Fractures occurred primarily along the particle/matrix interface. Photomicrographs. 5 ref.--J.C.J.(UK/US).
