Title:
金属材料を機械的に特徴付ける方法
Document Type and Number:
Japanese Patent JP5072237
Kind Code:
B2
Abstract:
Method for mechanical characterization of metallic material in comparison with the metal of a part that is to be repaired and for validation of a repair installation in which the part to be repaired is refilled with the repairing metal, e.g. using a TIG welding process. The method has the following steps: machining of a cavity in a bar (50) of the said metal; refilling of the cavity by the installation; cutting a test piece from the bar such that it has a central region made up entirely of the filler material and; subjection of the test piece to vibration fatigue testing. The invention relates particularly to turbine blades made from the titanium alloy Ti17.
