...) for 2 h. The specimen from the unfailed ductile strap was austenitized at an excessively high temperature of 1055 °C (1935 °F), oil quenched, and also tempered at 565 °C (1050 °F) for 2 h. Slow-bend tests and metallographic examination were performed on both specimens. The specimen from the failed strap...

... a transgranular mode with cleavage and ductile, dimpled shear. Hardness values as high as 35 HRC were measured in the bend area. The as-galvanized bolts fractured in a brittle manner. Failure was attributed to improper bending of the bolts, which provided a severely cold-worked bend area susceptible to strain-age...

Because of the low ductility of the material, redistribution of the load could occur only through crack initiation. This behavior may have been encouraged by inclusions near the surface, which served as stress...
