Abstract: A welded component includes at least one high temperature segment of a high alloy Cr steel with high creep strength and a low temperature segment of a low alloy steel with high toughness and/or a high yield strength which are connected materially to one another via a weld joint. In one such component a gradual transition of chemical, physical and mechanical properties in the joining area is achieved in that between the weld joint and the high temperature segment there are at least two successive clad layers of at least two lower alloy weld metals with a total content of elements which increase the creep strength, such as for example Cr, Mo, W and V, which total content decreases toward the weld joint, and/or an increasing total content of elements which increase the toughness and/or yield strength, such as for example Ni and Mn, which total content increases toward the weld joint.

Abstract: A two-layer nanotape that includes a nanoribbon substrate and an oxide that is epitaxially deposited on a flat surface of the nanoribbon substrate is described. The oxide is deposited on the substrate using a pulsed laser ablation deposition process. The nanoribbons can be made from materials such as SnO2, ZnO, MgO, Al2O3, Si, GaN, or CdS. Also, the sintered oxide target can be made from materials such as TiO2, transition metal doped TiO2 (e.g., CO0.05Ti0.95O2), BaTiO3, ZnO, transition metal doped ZnO (e.g., Mn0.1Zn0.9O and Ni0.1Zn0.9O), LaMnO3, BaTiO3, PbTiO3, YBa2Cu3Oz, or SrCu2O2 and other p-type oxides. Additionally, temperature sensitive nanoribbon/metal bilayers and their method of fabrication by thermal evaporation are described. Metals such as Cu, Au, Ti, Al, Pt, Ni and others can be deposited on top of the nanoribbon surface. Such devices bend significantly as a function of temperature and are suitable as, for example, thermally activated nanoscale actuators.
