Abstract: Fatigue lifetime enhancement of the holes formed in structural members occurs by introducing a cold working tool or interference fit fasteners fabricated from shape memory alloy materials. The tool may be employed to expand the wall of a hole while the tool material is raised above the critical transitional temperature. Then, upon lowering the tool material below the critical transitional material, it contracts permitting it to be withdrawn. Bushings and interference fit fasteners may be installed in holes formed in structural members when a shape alloy material bushing or fastener is heated above the critical transitional temperature so that an interference fit results and the hole is cold worked. If the alloy material is not cooled below the critical transitional temperature, the interference fit may be permanently maintained, thereby further enhancing the fatigue life of the members.
Abstract translation: 通过引入由形状记忆合金材料制成的冷加工工具或干涉配合紧固件，发生在结构件中形成的孔的疲劳寿命增强。 当工具材料升高到临界过渡温度以上时，该工具可用于扩大孔的壁。 然后，当将临时过渡材料以下的工具材料降低时，它合同允许其退出。 当将形状合金材料衬套或紧固件加热到临界过渡温度以上以形成过盈配合并且孔被冷加工时，可将衬套和过盈配合紧固件安装在形成于结构构件中的孔中。 如果合金材料没有冷却到临界过渡温度以下，则可以永久地保持过盈配合，从而进一步提高部件的疲劳寿命。
