High-speed machining is considered to be a promising technique due its advantages, such as high productivity and better product quality. With paradigm shift towards sustainable practices, the energy consumption analysis of high-speed also gaining ever-increasing importance. The current article addresses this issue presents detailed specific cutting (SCE) surface finish (Ra) during conventional ...

The goal of the present research is to develop a better understanding of the tensile response of open-cellular aluminum 6061 T6 alloy. Both tensile and compression samples of this metallic foam were tested under constant strain rate conditions at 293, 423, and 523 K. Scanning electron microscopy was performed on individual struts to assess the modes and mechanisms associated with fracture. Theo...

The role of loading rate and fluid properties in the fracture of piping under internal explosions is an important issue for designers and accident analysis. This was examined by fracture experiments on thin-walled and preflawed aluminum 6061-T6 tubes. The tubes were 1) statically loaded with oil, 2) statically loaded with nitrogen, and 3) dynamically loaded with gaseous detonations traveling at...

Effects of various surface treatments on hydrogen embrittlement 6061-T6 aluminum alloy were investigated. Rotary bending fatigue tests showed that electroless Ni-P plating reduced the strength considerably because absorbed into substrate by plating. These findings suggest possibility evaluating conducting rotary after

Continuous production of Al 6061-T6 particulate using modulation-assisted machining (MAM) is demonstrated. Superimposition of a controlled, low-frequency modulation in conventional machining causes chips to form as discrete particles. By adjusting the conditions, equiaxed, platelet and fiber-shaped particles having narrow size distributions can be produced. Large-strain deformation leads to mic...

Plane-strain machining can be used to impart large plastic strains in alloys that are difficult to deform by other severe plastic deformation (SPD) processes. By cutting at low speeds, the heating caused by friction with the tool can be reduced to insignificant levels. The utility of this approach for characterizing microstructure development in SPD is demonstrated using a variety of commercial...

The metallurgical modification in non-ferrous metal alloys is carried out to adapt not only physical or mechanical properties their applications, but also improve machinability. In the case of aluminum for optical reduction grain size an alteration aimed at adapting dimensions microstructure dimensional scale used machining conditions. cutting section are often much smaller than average size, w...
