Austenitizing temperature together with Homogeneity of Austenite
Austenitizing Temperature:
Austenitizing Temperature:Austenitizing is a oestrus handling process, that applies to the steel to modify the consummate construction into the austenite phase. this is possible when the steel heated upward to austenite temperature.The oestrus handling upward to austenitizing temperature is non constant, this differs for dissimilar composition of the steel.To accept command over the primary together with of import factors similar carbide solution, grain size together with the hardness of metallic etc.. this austenitizing temperature plays an of import role.
Homogeneity of Austenite:
Homogeneity of austenite is said to endure that the carbon content should endure uniform of austenite grains, At the fourth dimension of hardening when the temperature to a higher house the lower critical austenite is used to obtain inwards hypereutectoid steel, together with at the same fourth dimension when at that spot is a temperature of upper critical austenite is used to shape inwards proeutectoid ferrite.Due to the divergence inwards lower critical together with upper critical temperature to shape austenite, which is non a common formation at austenite, the carbon content is non inuniform.In this, the formation of a difficult construction is possible when at that spot is a high amount of carbon introduce inwards grain together with this type of organization undergoes to ho-hum charge per unit of measurement of cooling.And when at that spot is a depression amount of carbon content inwards grains together with thence they shape into bainite, due to the fast critical cooling rate.Homogeneity of austenite shows an touching on on hardness, construction etc..for a amend improvement inwards properties homogeneity of austenite is important, this tin endure formed when at that spot is a fast charge per unit of measurement inwards diffusion of carbon. together with if the carbon content is non uniform together with thence the hardness of metallic changes according to it.with the assist of austenitizing temperature oestrus handling the required hardness of the metallic is obtained.
