...Abstract Abstract The first step in the hardening of steel is getting it hot enough to form austenite, from which martensite can form upon quenching. Not all steels have the same austenitization requirements, however. High-carbon wear-resistant steels, such as bearing and tool steels, require...

The cage was made of aluminum bronze. The rings and balls were made of steel, equivalent to 52100 bearing...

...) are dangerously low for protection from brittle failures. For example, of all the steels used in an automobile, the maximum %C is only 0.4 in all parts except the springs, where %C is 0.6 (often 5160 in the leaf springs and 9260 in the coil springs), and the bearings, where %C is 1 (often 52100). This preference...

... for this alloy. Therefore, 5160 is closer to the pearlite composition than 1060, and the increase in the volume fraction pearlite formation as cooling rates are increased will be greater for 5160 than in 1060. As a second example, consider the widely used bearing steel 52100, which has a carbon content...

... that affects silicon nitride and most other ceramics is their low coefficient of thermal expansion. The silicon nitride coefficient of thermal expansion is 25% that of steel, so when a pressed-in bearing assembly heats up in service, the pressed-in outer race can become loose. Thus, to use all-ceramic bearings...
