Ferritic–martensitic dual-phase (DP) steels are prominent and advanced high-strength
steels (AHSS) broadly employed in automotive industries. Hence, extensive study is …

In-situ SEM can intuitively observe the changes in microstructure and microcrack initiation
during the deformation process of the specimen. In this paper, the microstructural evolution …

Metallic materials have long been used in a wide range of industrial applications due to their
outstanding physical and mechanical properties as well as high process latitudes …

The influence of martensite morphology and volume fraction on low-temperature impact
toughness of dual-phase (DP) steels was investigated by impact tests, nanoindentation …

Martensitic transformation significantly increases the strength of low-carbon steels, while it is
usually at expense of the formability and ductility. In order to further improve the mechanical …

A great challenge in producing TiC reinforced metal matrix composites is encountered to
directly add TiC particles into molten steel during casting owing to floating of nano-sized TiC …

According to Considère necking criterion, enhancing strength of a material will decrease its
elongation to failure, ie ductility, even if the strain hardening rate remains unchanged …

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 …

The excellent properties of transformation-induced plasticity (TRIP) steels with a lamellar
structure are generally claimed to mechanically stabilize retained austenite (RA) grains …

Steels with outstanding mechanical properties are desired in industrial applications.
Martensitic structure significantly increases the strength in low-carbon steels, but usually …
