equiaxed crystal मीनिंग इन हिंदी

Influenced by the alternating current field , all of the eutectic microstructure of al - 20si - 5fe - ti alloy changed into very small particles which is well - distributed on the base of a - al . electromagnetic stirring stimulates the forming of equiaxed crystal in al - 20si - 5fe - mn alloy . primary iron - phase is transformed from thick needle into smooth block
When the specimens are deformed in a long time at the optimal superplastic deformation condition , the microstructure is coarsened sharply . if the deformation time is shortened properly or the deformation temperature is decreased appropriately or strain rate is increased , homogeneous and fine equiaxed crystal microstructure can be obtained
