Title: Microstructure and mechanical properties of aluminium matrix composites reinforced by Al{sub 62}Cu{sub 25.5}Fe{sub 12.5} melt spun ribbon

Abstract

Aluminium matrix composites containing 15, 30 and 50 vol.% of pulverized Al{sub 62}Cu{sub 25.5}Fe{sub 12.5} (in at.%) melt spun ribbons have been prepared by a vacuum hot pressing (T = 673 K, P = 600 MPa). The microstructure of the initial ribbon and the composites was investigated using X-ray, scanning and transmission electron microscopy. In the as-spun ribbon the quasicrystalline icosahedral phase (i-phase) coexisted with the cubic copper rich β-Al(Cu, Fe) intermetallic compound. The phase composition of Al-Cu-Fe particles changed after consolidation process and the i-phase transformed partially to the ω-Al{sub 70}Cu{sub 20}Fe{sub 10} phase. Additionally, the Θ-Al{sub 2}Cu phase formed at the α(Al)/Al-Cu-Fe particle interfaces. With an increase in volume fraction of the reinforcement the hardness of the composites increased up to HV = 180 for the highest amount of added particles. The ultimate compression strength of the same sample reached the value of 545 MPa. - Highlights: • Al and 15, 30, 50% of pulverized Al{sub 62}Cu{sub 25.5}Fe{sub 12.5} melt spun ribbon were consolidated. • The initial ribbon consisted of the icosahedral i-phase and copper rich β-Al(Cu, Fe). • The i-phase partially transforms to ω-Al{sub 7}Cu{sub 2}Fe phase in all composites. • Increase of microhardness and compressive strengthmore » with content of reinforcement • Ultimate compression strength 545 MPa for 50% of added particles.« less

  • To increase the toughness of a metallic glass with the nominal composition Zr{sub 41.25}Ti{sub 13.75}Cu{sub 12.5}Ni{sub 10}Be{sub 22.5}, it was used as the matrix in continuous fiber composites reinforced with tungsten and 1080 steel wire. The composites were tested in compression and tension experiments. Tungsten reinforcement increased compressive strain to failure by over 900% compared to the unreinforced Zr{sub 41.25}Ti{sub 13.75}Cu{sub 12.5}Ni{sub 10}Be{sub 22.5}. The increase in compressive toughness comes from the fibers restricting shear band propagation, promoting the generation of multiple shear bands and additional fracture surface area. There is direct evidence of viscous flow of the metallic glassmore » matrix within the confines of the shear bands. Samples reinforced with steel had increased tensile strain to failure and energy to break of 13 and 18%, respectively. Tensile toughness increased as a result of ductile fiber delamination, fracture, and fiber pullout.« less
  • This paper discusses the mechanical properties of Titanium Carbide (TiC) particulate reinforced aluminium-silicon alloy matrix composite. TiC particulate reinforced LM6 alloy matrix composites were fabricated by carbon dioxide sand molding process with different particulate weight fraction. Tensile strength, hardness and microstructure studies were conducted to determine the maximum load, tensile strength, modulus of elasticity and fracture surface analysis have been performed to characterize the morphological aspects of the test samples after tensile testing. Hardness values are measured for the TiC reinforced LM6 alloy composites and it has been found that it gradually increases with increased addition of the reinforcement phase.more » The tensile strength of the composites increased with the increase percentage of TiC particulate.« less
  • The relationship between the structures and magnetic properties of Sm{sub 5}Fe{sub 17} melt-spun ribbons was studied. The melt-spun ribbons obtained by annealing of amorphous Sm{sub 5}Fe{sub 17} melt-spun ribbon consisted of the Sm{sub 5}Fe{sub 17} phase when annealed at 973 K for 0 h (i.e., when the furnace was immediately turned off after heating) or the Sm{sub 5}Fe{sub 17} phase together with a small amount of the SmFe{sub 12} phase when produced by annealing at 973 K for 1 h. The coercivity of the annealed Sm-Fe melt-spun ribbons was strongly dependent on the annealing conditions. The maximum coercivity of themore » annealed Sm{sub 5}Fe{sub 17} melt-spun ribbons exceeded 36 kOe.« less
  • In this investigation, processing of fully dense TiC-based cermets with iron aluminide (Fe-40 at. % Al) as a binder by pressureless melt infiltration has been clearly demonstrated. The carbide contents in these composites varied from 70 to 85 vol. %. Specimens with 30 vol. % intermetallic exhibited bend strengths of 1034 MPa, fracture toughness of 18 MPa{center_dot}m{sup 1/2} and a Rockwell (R{sub A}) hardness of 83.5. Further improvements in bend strengths may be possible by controlling the grain size and by modifications of the Fe40Al/TiC interface strengths.
  • Dense sintered composites of ZrO{sub 2} (2 mol% Y{sub 2}O{sub 3}) and WSi{sub 2} have been fabricated by hot isostatic pressing for 2 h at 1500 C under 196 MPa. They contain a small amount of W{sub 5}Si{sub 3}; during sintering, WSi{sub 2} decomposes into W{sub 5}Si{sub 3} and amorphous Si. The ZrO{sub 2} Particles in the composites consists of only t-ZrO{sub 2}. Microstructures and mechanical properties are examined, in connection with ZrO{sub 2} content. The fracture toughness and bending strength of the composite with 40 mol% ZrO{sub 2} addition are 7.1 MPa{center_dot}m{sup 1/2} and 1,011 MPa, respectively.
