Equal channel angular rolling (ECAR) process is one of the severe plastic deformation (SPD) methods that have been used to make ultra-fine grain (UFG) materials with improving the mechanical properties of samples. After performing the process at several paths, a large strain is applied to the material that can cause decreasing the grain size and improving the mechanical and physical properties ...

Experimental annealing of galena samples with known deformation histories shows that this mineral has the necessary properties to be a valuable source of information about low-grade deformational environments. Annealed galena displays recovery and/or recrystallization features dependent upon the type of texture inherited from the tectonic event, which in turn is closely linked to deformation te...

Three Bi2Sr2CaCu2O8 single crystals with di€erent annealing processes have been measured in terms of complex AC susceptibilities vn ˆ vn ÿ iv00 n (n ˆ 1; 3) to reveal the e€ect of ̄ux-pinning strength. The third harmonic susceptibility changes dramatically when the pinning strengths are di€erent due to di€erent annealing processes, although the fundamental susceptibilities are quite similar. Th...

Sputtered reactive multilayers applied as a heat source in electronic joining processes are 11 an emerging technology. It promises low-stress assembly of components while improving the 12 thermal contact and thus thermal resistance. The use of nanostructures can significantly enhance 13 the adhesion and reliability of joints between different materials. This work presents a 14 phenomenological ...
