Oct 23, 2020 · Deformation-induced martensitic transformations (DIMTs) have been widely observed in iron and ferroalloys under various mechanical loading conditions, thereby showing extreme scientific merits and engineering significance. Since deformations and fractures affect one another and reflect the relative movements of atoms, DIMTs often accompany fractures. In this work, molecular dynamics simulation
Martensitic Transformation in NiMnGa Single Crystals the polycrystalline state. In this respect, modeling and numerical simulation is of interest. This way, the behavior of ne martensite microstructures in single crystals and the related energy dissipation can be predicted to some extent. The modeling can be approached either on the atomistic level or on various continuum mechani-

Numerical Simulation of the Hot Stamping Process of Nov 10, 2020 · To avoid bainitic transformation, the cooling rate should be at least 27°C/s, so that the final microstructure is completely martensitic [7, 8]. The input parameters in the process simulation are shown in Table 1 and the considered punch and die face are shown in Figure 2. Fig. 2:A) Punch. B) Die face considered in the simulation.
