Influence of draw restraining force on the springback in advanced high strength steels [PDF]
, 2008 Draw beads are used in sheet metal forming processes to regulate material flow and achieve higher quality in the parts. The draw beads impose draw restraining force on the blank which eliminates defects such as wrinkling, tearing and reduces springback ...

Strong and ductile medium Mn steel without transformation-induced plasticity effect
Materials Research Letters, 2018 The conventional alloy design of medium Mn steel is to optimize the transformation-induced plasticity (TRIP) effect. Here we show that a dual-phase heterogeneous structure is sufficient to develop a medium Mn steel with high yield strength (∼1.2 GPa) and
