holding; thermal treatment 1 Introduction Aluminium based alloys can be welded by conventional fusion welding. The tungsten inert-gas welding process and friction stir welding process have been... particles if the alloy is stirred vigorously[4]. On the other hand, WANG[5] have recently shown another alternative to achieve the globular structure is semisolid thermal transformation, and it relies......
evaporation[8], thermal oxidation[9], ion beam sputtering[10] and RF sputtering[11]. GHODSI and TEPEHAN[12] studied the effect of heat treatment on optical properties of sol-gel Ta2O5 thin films. SPASSOV et al...
