The microstructure, microhardness, texture and corrosion resistance of cold-swaged and cold-wiredrawn copper rods were evaluated. Elongated grains along the deformation direction were observed for both materials and the width of these grains decreased with the increase of reduction in area. Wiredrawn copper rods have higher microhardness than the swaged rods for the same reduction in area. The copper...
We have investigated the shrinking phase transition of slightly ionized poly(N-isopropylacrylamide) (NIPA) gels. The macroscopic conformation change was observed on the heating process in two different methods; a continuous heating process and an isothermal process. It was found that the macroscopic behavior can be characterized by several conformation changes, the phase coexistence (or 'linked-dumplings'),...
