Deformation of Mg-?Mg17Al12 in situ composites: Room temperature mechanical behaviour, microstructures and mechanisms
نویسندگان
چکیده
Abstract Deformation tests at room temperature have been carried out on a series of in situ Mg-?Mg17Al12 composites with volume fraction ?Mg17Al12 phase varying between 20% and 60%. Regardless the fraction, these that are prepared by solidification consist magnesium-rich dendrites eutectic mixture. The mixture is made magnesium fibres embedded matrix formed phase, hard brittle complex metallic alloy. Compression shown global plastic deformation observed even though soft always enclosed one. According to strain-stress curve, proceeds two stages: first stage low stress (? ~ 100 MPa) strain (?e

Deformation at ambient and high temperature of in situ Laves phases-ferrite composites
The mechanical behavior of a Fe80Zr10Cr10 alloy has been studied at ambient and high temperature. This Fe80Zr10Cr10 alloy, whoose microstructure is formed by alternate lamellae of Laves phase and ferrite, constitutes a very simple example of an in situ CMA phase composite. The role of the Laves phase type was investigated in a previous study while the present work focuses on the influence of th...
متن کاملMicrostructures and mechanical performance of polyelectrolyte/nanocrystalline TiO2 nanolayered composites
Biological materials with hierarchically laminated structures usually exhibit a good synergy between strength and fracture toughness. Here, we show that a bio-inspired (polyelectrolyte (PE)/TiO2)4 nanolayered composite with a thickness ratio of TiO2 and amorphous PE layers of about 1.1 has been prepared successfully on Si substrates by layer-by-layer self-assembly and chemical bath deposition m...

متن کاملIn-situ deformation characterization of Nd-containing Mg alloys
An in-situ characterization technique combining mechanical testing inside a scanning electron microscope (SEM) with electron backscatter diffraction (EBSD) analysis was employed to study the tensile deformation behavior of Nd-containing Mg alloys over the temperature range of 50-250°C. EBSD data were collected before and after the experiments. The active slip and twinning systems were identifi ...
