Comparison of Hardness Values of Various specimens with different geometries and material properties after ECAP
Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...

متن کاملA Fiber Detector Radiation Hardness Test
An intense 146 MeV/c pion beam was stopped inside a scintillating fiber detector made out of 12 planes with 16 pixels each, where every pixel consists out of 8 × 8 scintillating fibers of 500 μm diameter dense packed. The detector was irradiated for 52 hours to more than 1 Mrad at its center. Before and directly after the irradiation the detector has been exposed to a particle beam to compare t...
متن کاملApplication of Chaos Theory in Hazardous Material Transportation
Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...
