Medium Manganese Steels: Part One

Medium manganese steels should be considered in the same circles of many of the technologically focused and well known materials in the automotive industry such as AHSS, DP, CP as well as second generation steels.
Medium-Mn steels show a strong tendency for transformation-induced plasticity (TRIP) or twinning induced plasticity (TWIP) depending on the stability of the retained austenite. Continue reading

Dynamic Strain Aging in Steel: Part One

Dynamic and static strain aging are the two main methods by which a material is further aged either during or after a period of plastic deformation.
Dynamic strain aging is specifically characterized by a rapid aging process which occurs during the actual straining and is associated with subsequent strength property advancements of the material. Continue reading

Steel Bending

There are five typical methods of bending currently used in industry today: rolling, incremental bending, hot bending, rotary-draw bending, and induction bending.
Although ISF is generally very slow, it is of interest because no or only a simple and cheap tool is required, making the process ideal for small-series production. Continue reading
