Fig. 9From: Experimental determination of TRIP-parameter K for mild- and high-strength low-alloy steels and a super martensitic filler materialFree dilatometric curve for steel S960QL with external load concept. With Gleeble ® 3500 facility measured free dilatometric curves. For t 8.5 = 10 s (black curve) the onset temperature of (γ → α)-phase transformation is T tr ≤ 420 °CBack to article page
