Nanostructured alpha-Ta films were sputtered at room temperature in order to synthesize material that had either compressive or tensile stress states (-1500 to 1000 GPa). The films were coated by magnetron sputtering at various pressures using Si substrates with and without an alpha-Ta underlayer. The roles of the substrate/film interface, underlayer, grain size and film texture were also investigated as a function of sputtering conditions and residual stress. (C) 2010 Acta Materialia Inc.
