Titanium alloys are considered difficult-to-cut materials due to their low machinability. Understanding the physical mechanisms occurring during cutting titanium is of particular interest improve Experimental and numerical investigations on Ti-6Al-4V alloy machining proposed in this paper. Orthogonal tests performed. The chip microstructure characterized using SEM observations coupled with EBSD...

This study investigated the high-speed cutting performance of 7050 aluminum alloy with prefabricated crystal orientations under dry-cutting conditions. Three specimens different were using pre-deformations 10, 15, and 20%, effects parameters on force, surface morphology, tool wear analyzed. The results showed that three-dimensional force initially increased then decreased increase in speed. In ...

In this work, we performed comparative studies of the effect of surface preparation of Ti6Al4V and Ti6Al7Nb biomedical alloys and the influence of endothelial cells on their corrosion behaviour in PBS (Phosphate Buffered Saline). Two different methods of surface modification were applied - polishing and sandblasting. The polished Ti6Al7Nb alloy was found to have the best resistance against gene...

scaling (that is, Dennard scaling) provided three benefits: doubling of integration capacity to deliver twice the number of transistors per unit area every two years at constant price, increased transistor performance, and reduced energy per transistor. With the steady erosion of the latter two benefits, the low-hanging fruit for performance increase has been to exploit integration capacity via...
