... of pearlite. Figure 15.1 is a TEM micrograph showing the pearlitic microstructure in a high-carbon steel rail. The interlamellar spacing between the ferrite and cementite phases is quite fine; regions where the lamellae are parallel or almost parallel are referred to as colonies. This remarkable composite...

...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...

... are not dissolved at the austenitizing temperature, then some carbon remains tied up in the carbides and is not available for martensitic hardening. Thus, undissolved carbides can actively decrease hardenability. This is especially important in high-carbon (0.50 to 1.10%) and alloy carburizing steels, which may...

..., the rate of transformation is very high. (In carbon steels, the length of the incubation period at this temperature does not exceed 1 or 1.5 seconds.) In between two curves, the austenite is in the process of transforming to pearlite, and hence both austenite and pearlite will coexist. The amount...
