... steel. They were barrel finished to remove burrs and hardened and tempered to 45 to 52 HRC. The fasteners were electroplated with zinc and coated with clear zinc dichromate. During attachment of the fabric to the furniture, approximately 30% of the fasteners cracked and fractured as they were...

Machining and other finishing processes introduce surface residual stresses that are often tensile and may be significant, especially in parts with thin sections. Grinding processes can be controlled to minimize...

... also record their appreciation for Mr. B. Khalkho for neatly typing the manuscript. The ICDP work rolls used in the finishing stands of this particular HSM are of 810 mm barrel diameter (nominal) and 2000 mm barrel length. The hardness on the working surface of new rolls ranges between 80 and 85...

... or at the transition from the thread to the shank. Failure origins are often imperfections in the metal caused by segregation in the form of inclusions, such as sulfides and oxides in the ingot, or by folds, laps, or seams that have formed because of faulty working either in the semifinishing or finishing mills...

One form of brittle fracture occasionally encountered results from hydrogen absorption in martensitic structures, which occurs in electroplating or other cleaning or finishing processes. Corrosion contributes to spring failure in much...
