Laser shock peened gas turbine engine intermetallic parts |
摘要 |
An intermetallic article such as a gas turbine engine component and method of manufacture thereof includes a region having compressive residual stresses imparted by laser shock peening (LSP) extending into the article from a laser shock peened surface. One embodiment includes a turbine or compressor blade with an intermetallic airfoil having a leading edge and at least one laser shock peened surface extending radially along at least a portion of the leading edge with a region having compressive residual stresses imparted by laser shock peening (LSP) extending into the intermetallic airfoil from the laser shock peened surface.
