The embrittlement range Study guides, Class notes & Summaries

Graphitization - Answer A change in the carbide phase of C/S and 0.5 Mo steels after long term exposure to 800° F to 1100°F temperatures causing decomposition into graphite nodules. Softening(Spheroidization) - Answer A change in the microstructure of steels after exposure in the 850 to 1400 range, where the carbide phases in C/S are unstable and may agglomerate from their normal plate-like form to a spheroidal form. Temper Embrittlement - Answer The reduction in toughness due t...
