High strength-elongation product of Nb-microalloyed low .

Highlights As-treated Q–P–T steel covers a wide spectrum of strength and elongation. High strength results from martensite laths and NbC or ɛ-carbides in martensite matrix. Good ductility is attributed to TRIP effect from retained austenite flakes. Si can only suppress the formation of Fe 3 C in short tempering time steel. Si cannot suppress the formation of ɛ-carbides in low tempering ...

Nano-engineered steels for structural applicatio

Steel is one of the most widely used engineering materials in the world. Its pre-eminent position amongst the engineering materials arises due to the abundance and low cost of its main constituent, i.e. iron, and its amenability to produce a wide variety of engineered microstructures with superior properties, and recyclability. Currently, there is a growing awareness about the potential ...

and strong. Even in the case of steel, the martensitic trans­ formation does not result in high strength if the carbon content is low. nl A martensitic transformation is made possible by an interface which couples the lattice of the parent phase to that of the martensite with some degree of coherency. As the
