“…Similar results were reported for medium‐Mn steels. [ 14–16 ] However, in their case, mechanical properties are more strain rate dependent. [ 16 ] Some works reported that the TRIP effect is delayed or limited due to the temperature increase caused by the increased strain rates [ 14,15 ] leading to a decrease of tensile strength.…”

“…With increasing the strain rate above 1 s −1 , the increase of total elongation and ultimate tensile strength took place. He et al [ 16 ] noted that the strain rate affected the elongation of 3.5% and 10% medium‐Mn steels. They reported that the elongation values decreased in both steels at strain rates up to 450 s −1 .…”

The comparison of the dynamic mechanical behavior and microstructure of two medium manganese sheet steels (3Mn–Al and 5Mn–Al) alloyed with aluminum is aimed. Mechanical properties under dynamic tensile loads are determined by means of rotary hammer dynamic tests at strain rates of 250 and 1000 s−1 and analyzed together with the results of static tensile test. It is found that the results are significantly affected by the variations in Mn content in the range from 3 to 5 wt%. In both steels, the tensile strength increases with increasing strain rate, but the variation in the strain rate range has a moderate effect on mechanical behavior. The highest ultimate tensile strength of 1475 MPa is measured in the 5Mn–Al steel, whereas the 3Mn–Al steel is characterized by better total elongation due to a larger fraction of retained austenite and more pronounced transformation‐induced plasticity effect. The results show that the mechanical properties of 3Mn steel are more strain rate sensitive than those of 5Mn steel. The microstructural features are characterized qualitatively and quantitatively by X‐ray diffraction, scanning electron microscopy, and electron back‐scattered diffraction techniques.

“…When the dynamic constitutive model is used to fit the experimental data, the strain rate hardening coefficient is generally given by the yield strength (σ s ) of the material, so it is necessary to accurately fit the yield strength first. The logarithmic and exponential functions were used to fit the yield strength of 10Mn steel [36] and 6016-T6 [33] aluminum alloy, respectively. The fitting results are shown in figures 2 and 3.…”

In this paper, the H/V-JC/CS dynamic constitutive relation suitable for a wide range of strain rates is proposed. Based on the experimental data in the existing literatures, the parameters of the H/V-JC/CS constitutive model for metal materials are calibrated by using the global optimization algorithm, which has high accuracy, convenient application, and is unlimited in number of parameters. The obtained parameters do not depend on the initial value and are the global optimal combination. The corresponding ABAQUS visual user material (VUMAT) subroutine is compiled and imported into the finite element analysis for the dynamic response of the honeycomb panel structure. The influence of geometric parameters on the energy absorption effect of honeycomb panels under impact load is explored. The research shows that the proposed H/V-JC/CS constitutive model can well describe the mechanical behavior of various metals in a wide range of strain rates under impact load, and can be used in ABAQUS dynamic explicit environment. It provides a high-precision engineering application analysis model for metal structures under dynamic load.

“…As a potential third-generation high-strength steel, the medium manganese steel has broad application prospects [1][2][3][4]. Due to the high strength of medium manganese steel, it is easy to have problems such as large springback, poor dimensional accuracy and even cracking during traditional cold stamping [5].…”

As a potential third-generation high-strength steel, the medium manganese steel has broad application prospects. Hot stamping technology can effectively solve the problems of large springback and large forming resistance in the cold stamping process of medium manganese steel. However, the hot stamped parts have low elongation, which cannot meet the crashworthiness requirements. The quenching-partition (QP) heat treatment process can greatly increase the elongation of the part without reducing or slightly reducing the material strength. The quenching temperature, partitioning temperature and partitioning time have a great influence on the microstructure and mechanical properties of the hot stamped part. In order to obtain the optimal process parameters, numerical simulation of the QP process based on three models were conducted. The results showed that the CCE model is simple to use but with large error. The results obtained from the carbon partition model considering interfacial migration agreed best with the experimental results.
