FORMATION OF FACE-CENTERED-CUBIC TITANIUM ON A NI SINGLE-CRYSTAL AND IN NI TI MULTILAYERS/

The artificial layering of metals can change both physical and structu ral characteristics from the bulk. The stabilization of polymorphic me tallic phases can occur on a dimensional scale that ranges from single overgrowth layers to repetitive layering at the nanoscale. The sputte r deposition of crystalline titanium on nickel, as both a single layer and in multilayer form, has produced a face-centered cubic phase of t itanium. The atomic structure of the face-centered cubic titanium phas e is examined using high resolution electron microscopy in combination with electron and x-ray diffraction.
