Pearlite period

Period of time until the appearance of pearlite in the TTT diagram of iron materials.


pearlite periods are necessary in the production of ADI, for example,

so that during quenching of the austenitizing temperature, the pearlite

range (the pearlite peak) is not passed. In practical alloying, this is

usually achieved with alloy elements such as copper nickel and

molybdenum (s. Bainitic cast iron).
