... profiles of case-hardened and through-hardened bearing steels Similarly, nitriding of bearing steels is another case-hardening process gaining traction ( Ref 3 , 115 – 118 ). This process is performed similarly to carburizing, except it is performed after tempering and provides similar benefits to...

... performed satisfactorily when fired up at regular intervals. Although this boiler was in use in a working operation, there are many boilers of a similar age on vintage traction engines in the hands of New Zealand hobbyists. Annual inspections of these boilers is mandatory, and it was during such an...

... contributing factors. It may be helpful to delineate the factors that did not contribute to failure, as this information can also help to avoid recurrence of the failure. Labeled grades of wires are of historical significance, but are somewhat vague. The following grades have been specified: iron, traction...

... anisotropic materials. Although many practical stress states can be analyzed in two dimensions, the more complex 3D case is now examined. Complicated loading and/or geometry may induce a stress state in which none of the stress components is zero. For example, normal and tangential surface tractions as...
