Scope
This section specifies the determination methods for the bending strength (σbb) and fracture toughness (KⅠC) of rare earth permanent magnet materials. This section is applicable to the determination of the bending strength and fracture toughness (KⅠC) of brittle fracture rare earth permanent magnet materials. The determination range of bending strength is 20 MPa to 2,000 MPa, and the determination range of fracture toughness (KⅠC) is 0.5 MPa·m1/2 to 50 MPa·m1/2.
