Computational Design of High Temperature Alloys

The development in computational simulation techniques has brought significant progress in the realization of computational alloy design. The advantages are most significant when developing novel materials of which the research & development cycles are particularly time and energy (and hence cost) consuming, such as high-temperature alloys....

Oxidation phenomena in advanced high strength steels: Modelling and experiment

Galvanized advanced high strength steels (AHSS) will be the most competitive structural material for automotive applications in the next decade. Oxidation of AHSS during the recrystalization annealing process in a continuous galvanizing line to a large extent influences the quality of zinc coating on the final galvanized steel product. For...

Kinetics of internal oxidation of Fe-Mn-Cr steel alloys

Selective oxidation behaviour of Fe-Mn-Cr steel alloys annealed at 950°C in Ar plus 5 vol.% H2 atmosphere under different annealing time and dew points was studied. The Fe-Mn-Cr steel alloys are externally oxidized when annealing at dew point of -45 °C, while internally oxidized at dew points of -10 and 10 °C. The internal oxides formed in the...

Computational design of heat resistant steels with evolving and time-independent strengthening factors

Alloy design by the traditional trial and error approach is known to be a time consuming and a highly cost procedure, especially for the design of heat resistant steel where the feedback time is intrinsically long. The significant developments in computational simulation techniques in the last decades have made a theory-guided computational...

Kinetics of Wüstite Formation and Reduction of Manganese alloyed Steel

The oxidation and reduction kinetics of a 1.7 wt.% Mn steel alloy with 0.1 wt.% C was studied in different ?CO?_2/CO mixtures and at different temperatures. The external iron oxide growth, the internal alloying element oxide formation and the reduction of iron oxides were observed with thermogravimetry (TG). The oxidation at 750 ? follows a...

Cyclic Partial Phase Transformations In Low Alloyed Steels: Modeling and Experiments

Mechanical properties of low alloyed steels are directly determined by their microstructures. Thanks to versatility in their microstructures, the mechanical properties of low alloyed steels are much more adjustable than other materials. In the industry, one of the most effective ways to obtain the microstructure for the targeted mechanical...
