Development of high strength and ductile ultra fine grained dual phase steel with nano sized carbide precipitates in a V–Nb microalloyed steel

Optimization of electrical conductivity and strength combination by structure design at the nanoscale in Al–Mg–Si alloys

“…Such a rough estimate, considering a simple additive contribution of each feature has already been relatively successfully applied to other UFG materials [14,50,51] and also Al-Mg-Si alloys processed by HPT [14,52]. It is proposed to use it here also as a first approximation and its validity will be discussed in the following, especially when UFG structures are considered.…”

Influence of annealing process on microstructure and mechanical properties of C-Mn dual phase steel

“…Dual phase steel grades (hard martensite embedded in a soft ferrite matrix) offer attractive properties, such as continuous yielding, high work hardening rate, good uniform elongation and relatively high formability, which are of considerable interest for applications in the automotive industry [1][2][3][4].…”

Atom Probe Tomography Study of Multi-microalloyed Carbide and Carbo-Nitride Precipitates and the Precipitation Sequence in Nb-Ti HSLA Steels

“…[1][2][3][4][5][6][7][8] The combination of these microalloying elements with interstitial solutes, such as C and N, leads to the formation of carbides, nitrides, and complex carbo-nitrides. [7,[9][10][11][12][13] In general, Ti, Nb, and V facilitate grain refinement through precipitation in the austenite and contribute to dispersion hardening through carbide precipitation in ferrite.…”

“…[1] In contrast, V contributes more to precipitation strengthening because it has a low solubility in ferrite and precipitates readily at lower temperatures. [1,2] The relative contribution of microalloying elements is determined by the solubility of their carbide/nitride/carbo-nitride phases in the microstructure.…”
