    摘要： A turbine blade 12 includes at least two blade segments 16,18. Each blade segment includes first and second shells 21,23 joined together, a base region 22, at least one joint region 24 including a mating face 28. Each of the first and second shells includes an outer skin 26,27, a base spar cap 46 attached to an inner surface of the outer skin in the base region, a joint spar cap attached to the inner surface of the outer skin in the joint region and adjacent to at least a portion of the base spar cap. The joint spar cap 34 includes holes in the mating face of the joint region. The turbine blade 12 further includes fasteners 64,66 within the holes for securing the at least two blade segments together.

    摘要： Titanium-containing articles having improved surface finishes and methods for changing the surface of titanium containing articles, for example by removing overstock, are provided. One example method includes passing a fluid at high pressure across a surface of an titanium aluminide alloy-containing article, for example, a turbine blade, at high linear speed and deforming the surface of the titanium aluminide alloy-containing article, and removing material from the surface of the titanium aluminide alloy-containing article. Though aspects of the invention can be used in fabricating high performance turbine blades, the methods disclosed can be applied to the treatment of any titanium-containing article for which it is difficult to obtain an improved surface finish.
