[ 1 ] - Study of the effects of lower bainite volume fraction on tensile and impact properties of D6AC medium carbon low alloy ultrahigh strength steel

The effects of lower bainite volume fraction on tensile and impact properties of D6AC ultrahigh strength steel were studied in the current work. To obtain mixed microstructures containing martensite and different volume fractions of the lower bainite, specimens were austenitized at 910° C, then quenched in a salt bath of 330°C for different holding times, finally quenched in oil. In order to ob...
