The method of Si substituting for Al was proposed to design a novel hot-rolled lightweight
steel with ultra-high ultimate tensile strength (2046 MPa) and good total elongation after …

Weight reduction from down-gauged high-strength steels has been an important issue in
automotive industries to improve fuel efficiency. In addition to lightweight needs, automotive …

In this investigation a new third generation advanced high strength steel (AHSS) has been
developed. This steel was synthesized by austempering of a low carbon and low alloy steel …

The automobile industry pays lots of attention on a new kind of steel with excellent
combination of strength and ductility as well as the lower density, aiming at developing more …

The need for lightweight materials has been an important issue in automotive industries to
reduce greenhouse gas emission and to improve fuel efficiency. In addition, automotive …

Lightweight steels containing a considerable content of Al show high specific strength and
ductility, but there are some drawbacks such as low yield strength and stringer-type bands …

An ultrahigh strength and enhanced ductility cold-rolled medium-Mn steel was manufactured
via intercritical annealing. The fine lamellar and equiaxed duplex microstructure, austenite …

High-carbon martensite steels (with C> 0.5 wt.%) are very hard but at the same time as brittle
as glass in as-quenched or low-temperature-tempered state. Such extreme brittleness …

The high strength of martensitic steel can be attributed to its fine hierarchical structure and
high dislocation density. To further improve the mechanical properties of low-carbon …

Advanced high strength steels containing metastable austenite are of considerable interest
due to the combinations of strength and ductility that are achieved via austenite …
