The melting behaviour of grain boundaries in bicrystals of aluminum and zinc has been examined. The melting temperature of the boundary was found to be the same as that of the bulk material within an experimental uncertainty of 0.05"C for aluminum and 0.02"C for zinc. Bicrystals of zinc separated at
The energy-misorientation relationship of grain boundaries in copper was measured by recording the rotation rate of a single crystaf sphere of copper sintered on to a flat single crystal of the same material. The results obtained suuggest that low-energy boundaries may exist at non-highcoincidence o
## Abstract Thin films of inorganic materials are used in diverse applications, typically in polycrystalline form due to their relatively simple production. We have used enhanced piezoresponse force microscopy to investigate the domain distribution within neighbouring grains in thin polycrystalline
