austenite

Quenching steel results in transformation of austenite into martensite, it is not completely transformed. There are some of the crystals of austenite that remain unchanged and are not affected by quenching below martensite-finish temperature. This can further be transformed into martensite, through slow cooling of the metal at extremely lower temperatures. Normally, cold treating includes […]

Proper treatment of heat requires precise-control over temperature, cooling rate and time at a particular temperature. Normally, heat treating process starts from heating alloys beyond upper transformation temperature. The exception to this is tempering, aging and stress relieving. This upper transformation temperature is known as “arrest” because at upper transformation temperature nothing noticeable happens. So, […]

A eutectoid alloy is comparable in nature to a eutectic allow. A eutectic combination is described by having a solitary dissolving point. This liquefying point is lower than that of any of the constituents and no change in the mixture will bring down the dissolving point any further. At the point when a liquid eutectic […]
