	657 x 556 77KB GIF	OIM™ (Orientation Imaging Microscopy) map showing grains with different orientations in copper -- a possible substrate material for coated conductors. The different colors represent orientation variations of more than two degrees; the black lines are low-angle grain boundaries. From APS talk "OIM™ Characterization of Metal Substrates for YBCO Coated Conductors," March 1998, , Babcock, Larbalestier, Thieme, Fritzemeier (American Superconductor collaboration)
	648 x 682 196KB JPG	Backscattered Electron Kikichi Patterns from two adjacent grains in copper (left) and OIM™ indexing of the patterns (right). The movement of the <110>-type pole indicates the changing orientation from grain to grain. Copper is a non-magnetic alternative to nickel for use as a substrate for YBCO coated conductors.
