Cross rolling followed by intercritical annealing was proposed as an alternative route for processing of dual phase (DP) steels, which led to fine recrystallized ferrite grain size and uniformly distributed martensite islands. Accordingly, the processed low-carbon steel showed better strength-ductility trade off, higher hardness, and greater work-hardening exponent.

通过交叉轧制和临界退火提高双相钢的机械性能

提出了交叉轧制然后进行临界退火的方法，作为双相（DP）钢加工的替代方法，这导致了细微的再结晶铁素体晶粒尺寸和均匀分布的马氏体岛。因此，加工的低碳钢表现出更好的强度-延展性折衷，更高的硬度和更大的加工硬化指数。
