Metallic article with integral end band under compression |
摘要 |
An article made of a metallic material and comprising a body and a body end portion integral with the body, includes a band of the metallic material at the end portion substantially through the entire end portion, the band being under a compressive stress greater than the body. An example of the article is a turbine engine balding member in which the body is the airfoil of the member and the band is disposed at the radially outer tip portion of the airfoil. One method for providing the band includes performing roller deformation on the end portion until a desired amount of compressive stress is developed in the band substantially through the entire end portion.
