摘要： PROBLEM TO BE SOLVED: To provide a crankshaft manufacturing method that can facilitate light weight of a crankshaft at a low cost and that can satisfy material properties required for the crankshaft along the axial direction.
SOLUTION: This is a method of manufacturing a crankshaft by joining a plurality of joining members to each other. In the method, in joining the joining members 10A, 10B..., those that are sectioned in the faces 30a, 30b...crossing the axial line L of the crankshaft 1 are used as the joining members 10A, 10B.... The joining members are joined by liquid phase diffusion joining by interposing, between the joining members, a low melting point joining material 60 which has a lower melting point than that of the joining members containing a boron element.

摘要： PROBLEM TO BE SOLVED: To perform delayed fracture test in a test environment that is close to an actual environment in which delayed fractures occur. SOLUTION: A fixture 20 for test to be used for delayed fracture test comprises a through hole 22 for inserting a test piece 10; a reservoir part 24 for forming a reservoir of a test liquid 30 in the inside; and an inlet 26 for injecting the test liquid 30. The test piece 10 is inserted in the through hole 22 of the fixture 20 for test. A gap between the through hole 22 and the test piece 10 is sealed with a gap-sealing member 28. The test liquid 30 is injected into the reservoir part 24 from the inlet 26 to expose the test liquid 30 to the test piece 10. The inlet 26 is sealed with an embedded plug 32 and the sealing member 34, to shut off an exposed part from an atmospheric environment into a sealed condition. Both ends of the test piece 10 are mounted to a grip part 40 of a tensile tester, loaded with prescribed stress, and held in a prescribed temperature environment in a temperature test chamber 40. Actual bolt can also be used as a test piece. COPYRIGHT: (C)2007,JPO&INPIT
