The casting and hot rolling process is a most important and widely used industrial route to produce aluminum alloy sheet[I]. Because rolling is such a high volume process and the capital expenditure in plants and fabrication facilities is so large, even small cost savings or increases in efficiency can result in a very large total money savings[2, 3]. To remove the very costly and time-consumin...

A method of measuring biaxial stress-strain curves for sheet metal samples subjected to large plastic strains is described for one example aluminum alloy (AA 5754-O). The method uses a portable X-ray diffraction (XRD) system to measure in situ stresses during tensile deformations. Calibration of X-ray elastic constants and the effects of texture and intergranular stresses are discussed. Uniaxia...

In recent years, the use of aluminum alloy has tended to increase for building lightweight automobiles to reduce their automotive weight, which is helpful to save energy and protect the environment. In order to join aluminum alloy, a flat-clinching process combined with material forming technology was investigated to join aluminum alloy sheets using an experimental and a numerical method. Al106...

This study evaluated the performance of aluminum-copper alloy filtration, without the original aluminum filter, for dental radiography in terms of x-ray energy spectrum, air kerma rate and image quality. Comparisons of various thicknesses of aluminum-copper alloy in three different percentages were made with aluminum filtration. Tests were conducted on an intra-oral dental x-ray machine and wer...

Recent developments in incremental sheet forming have resulted the creation of novel manufacturing processes that are highly adaptable and could bring significant economic benefits for advanced technologies low-volume production. In this manuscript, following variables were examined: variation deformation forces a part with pyramidal trunk shape; deformations thinning Al 3003 material during pr...
