The effect of cooling rate on structure and properties of a HSLA forging

The mechanical properties along with microstructures of HSLA-80 steel, forged in two stages and subsequently cooled at three different cooling rates, were studied. The fastest cooling rate produced maximum strength due to formation of fine bainite and martensite where as intermediate cooling rate re...

Zusammenfassung:The mechanical properties along with microstructures of HSLA-80 steel, forged in two stages and subsequently cooled at three different cooling rates, were studied. The fastest cooling rate produced maximum strength due to formation of fine bainite and martensite where as intermediate cooling rate resulted in maximum toughness values owing to predominantly bainitic microstructure.
