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 […]

Heat treatment physical process provides an effective approach to the properties of metal by controlling the rate of dissemination and the rate of cooling inside the micro-structure after the metal is heated. Metallic materials comprise of a microstructure of little precious crystals called “grains” or sometimes crystallites. The nature of the grains is also the […]
