This book was released on 2010 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, bulk nanostructured materials processed by methods of severe plastic deformation (SPD) have attracted the growing interest in academia and industry. This interest is caused not only by unique physical and mechanical properties inherent to various nanostructured materials, e.g., higher hardness and Young's modulus, etc, but also by the ability of SPD process to create bulk nanostructures. In this dissertation work, air blast shot peening (ABSP) a SPD process using very high shot velocities was used to achieve high strain rates of surface material causing bulk surface nanocrystallization. ABSP process parameters has been extensively investigated to understand their effects on bulk nanostructures formed on steel (AISI 1018, AISI 1045, AISI 1075) and aluminum (Al 6061, Al 7075) components. Finite element simulations have also been carried out to study the effect of peening parameters on stress/strains and temperatures in the peened component. The peened samples have been characterized using optical microscope and scanning electron microscope (SEM) and the grain size shows a gradual reduction from the subsurface to the surface. The grain size of the steel and aluminum peened samples based on the TEM images was less than 50 nm. The nanocrystalline (NC) zone showed a considerably higher hardness as compared to the unpeened material. Lastly a study of corrosion characteristics of the NC layers fabricated on steel and aluminum alloys indicated a higher corrosion potential of the NC layers as compared to the bulk material.

Download or read book Synthesis of Bulk Nanostructured Al Alloys with Ultra High Strength and Wear Resistance for Army Applications written by and published by . This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis/processing of nanostructured (amorphous or ultra fine grained) materials was studied via various processing routes such as gas atomization, melt spinning, cryomilling, equal-channel angular pressing (ECAP) and conventional consolidation. Microstructures and mechanical properties of both the amorphous powders and consolidated bulk materials were characterized. The amorphous alloy of A185Ni10La5 (at.%) was fabricated in terms of melt-spun ribbons and particularly, gas-atomized powders (25 micrometers). The kinetics and microstructure evolution during the devitrification process were carefully investigated using DSC, XRD. SEM, TEM, and SAxS. It was found that quenched-in fcc-Al nuclei present in amorphous Al85Ni10La5 powders. Annealing at 235 degrees C leads to growth of the quenched-in nuclei with the grain size stabilized around 10 nm. With increasing annealing temperatures (i.e., at 245 degs C, 250 degs C and 263 degs), the devitrification takes place via eutectic crystallization with a resultant grain size around 20 nm. At the temperatures283 degs, the devitrification tends to complete in a short time ( -5 min), however, this alloy shows excellent thermal stability to resist grain growth. The influence of devitrification, under various annealing temperatures, on mechanical response was studied by nanoindentation technique. Bulk nanostructured materials were synthesized by consolidating the amorphous Al85Ni10La5 alloy powder with 5083 Al alloy powder milled under cryogenic temperature (cryomilling). The addition of cryomilled 5083 Al alloy is to further increase the specific strength for the bulk materials (e.g.,>1000 MPa in compression with the density -2.9 g/cc). The bulk nanostructured material also shows high strength at elevated temperatures (i.e., 400 MPa in compression at 200deg). At room temperature the tensile properties were found be lower than the compressive properties and this differential effects should be investigated in the future st7.
