Summary: A remarkable plastic flow instability is observed during tensile deformation of the commercial 304 stainless-steel sheet at room temperature. The occurrence of plastic flow instability in 304 is dependent on the strain rate and specimen gage length. Moreover, the enhanced strain hardening resulting from deformation-induced martensitic transformation facilitates the orderly propagation of the strain-localized band.

Summary: The microstructure adjustment is crucial for the optimal design of high-performance duplex low-density steels to accommodate deformation at different strain rates. In this study, Fe-8Mn-6Al-0.4C low-density steel was annealed to obtain duplex microstructures with an inhomogeneous distribution of austenite grain sizes, and tensile tests were performed at two strain rates. The mechanical behavior of the steel was found to depend mainly on the mechanical stability of austenite.

Summary: The study investigated the mechanical behavior of steels with metastable austenite and found that high strain rates can inhibit martensitic transformation, leading to a limitation in alloy design. Experimental results showed that as the strain rate increased, martensitic transformation sequences changed, ultimately suppressing DIMT kinetics. The work provides methods to enhance DIMT behavior by tailoring martensitic transformation sequences, offering a comprehensive explanation for the strain-rate dependence of DIMT.

Summary: This paper investigates the thermodynamic nature of strain rate effect of phase transition materials by studying temperature evolution during phase transition at different strain rates. A thermally-mechanically coupled model is proposed based on laws of thermodynamics and principle of maximum dissipated energy. The model predicts that temperature profile varies around the moving phase boundary in quasi-static case, while thermal response of the specimen reaches homogeneously in dynamic case due to random nucleation.

Summary: This study investigates the impact performance of AlCoCuFeNi HEA/graphene composites using molecular dynamics simulations and finds that graphene can enhance the impact properties of the HEA. The enhancement is mainly attributed to the strong load carrying ability of graphene, although it can also have a negative effect on the impact force of HEA by breaking the structure continuity. Moreover, graphene significantly affects the stress distribution and dislocation behavior at the HEA/graphene interface during the impact process.

Summary: We present a conceptual design and experimental realization of a ternary Heusler-based ferromagnetic martensitic phase transformation alloy Fe48Mn24Ga28 which exhibits asymmetric magnetostructural coupling between the forward austenite-to-martensite and the reverse martensite-to-austenite phase transformations. By tuning the Curie temperature of the high-temperature austenite to be within the thermal hysteresis of the first-order phase transformation, dissimilar change in magnetization can be associated with the forward and reverse phase transformations, respectively. Our findings suggest the intricate correlation between magnetostructural coupling, thermal hysteresis, and magnetic-field-induced phase transformation, which can be utilized for designing magnetic phase transformation alloys with extended functionalities.

Summary: The mechanisms contributing to the excellent mechanical properties of the ultrafine-grained Fe-23 wt.%Mn alloy processed by heavy ausforming are revealed. The alloy exhibits high ductility and resistance to cracking, contrary to the behavior of typical ultrafine-grained alloys. This is attributed to the gradual deformation-induced epsilon-martensitic transformation and to the large plastic co-deformation of the UFG epsilon-martensite.
