EXPLOSION WELDED GAS TURBINE SHROUD AND METHOD FOR FORMING EXPLOSION WELDED GAS TURBINE SHROUD

摘要

PROBLEM TO BE SOLVED: To provide an explosion welded gas turbine shroud and to provide a method for forming the explosion welded gas turbine shroud.SOLUTION: The explosion welded gas turbine shroud and the method for forming the explosion welded gas turbine shroud are disclosed. The explosion welded gas turbine shroud includes a first alloy welded to a second alloy. In the explosion welded gas turbine shroud, the first alloy forms at least one part of a high temperature gas passage or the expansion region of the gas turbine shroud includes the first alloy. The method includes a step of forming the gas turbine shroud by explosion welding the first alloy to the second alloy.
