“…Various studies have investigated the cold rolling parameter dependence on microstructure evolution in various steel grades, including twinninginduced plasticity (TWIP) steel, medium-carbon steel, extra low-carbon steel, quench and partitioning (Q&P) steel, lowdensity steel, and stainless steel. [67][68][69][70][71][72][73] Friction also affects the microstructure evolution and mechanical properties. The main mechanism for friction effect during cold rolling is heat transfer.…”

“…According to previous studies, TWIP [ 19,55 ] as well as TRIP [ 56,57 ] strengthening mechanism, and the SRO [ 58,59 ] strengthening effects play the significant roles in controlling work hardening behavior. Higher work hardening rate means a better combination of tensile strength and uniform elongation, exhibiting success in Fe–Mn–C–Al low‐density steel design for automotive and other lightweight industrial applications.…”

Al steel exhibits lightweight and outstanding mechanical properties, bringing considerable applications in vehicle, airplane, and mining industries as structural materials and components. The addition of C and Al elements into Fe-Mn iron matrix, following with subsequent heat treatment, plays an important role in microstructure controlling, such as single phase (austenite structure) or duplex phases (mixing with ferritic and austenite) matrix, as well as the short range order and κ-carbide precipitation. These microstructural evolutions considerably influence the mechanical properties of low-density steel, especially of the work hardening, tribological, cryogenic, and hydrogen embrittlement performance. The current article introduces the progress of alloying and heat treatment, as well as the subsequent heat treatment effects on microstructural evolution and mechanical properties of Al-containing low-density steel. The recent research progress on Al-containing low-density steel shall provide a valuable source of ideas for high-quality, low-density steel design, and engineering applications.

“…Pre-strain is one of the important methods to change metal properties. For example, applying pre-strain can affect metal microstructure [1][2] , strength [2][3] , stiffness, creep property [4][5] , fatigue property [6][7] , forming performance [8] , and so on. The reason for enhancing strength mainly lies that dislocation density increases and dislocation entanglement become worse after applying pre-strain.…”

Applying pre-strain can not only change the microstructure and the mechanical property of metal material but also affect sheet metal stamping ability. In this paper, taking H260 low-alloy steel and TA2 titanium alloy as experimental materials, pre-strain ranging from 0 to 0.16 was applied using the one-step and the multi-step method respectively. Microstructure observation, tensile test, bending test, and cup bulging test were conducted on the pre-strained samples. Results show that in the pre-strain loading stage, the slipping and twinning deformation occurs in the TA2 alloy sample while dislocation sliding mainly happens in H260 low-alloy. With pre-strain increasing, the product of ultimate tensile strength and elongation rate gradually decreases, and the true ultimate tensile stress and accumulating elongation change rarely. The “product of yielding strength and elongation rate” can be enhanced by applying a pre-strain of 0.04 on the condition that plasticity is still at a high level. In the pre-strain range of 0 - 0.16, a bending test with a 30.8 °-opening angle can be completed on H260 steel. The springback angle changes from negative to positive with an increase in pre-strain. The bending ability of TA2 titanium alloy is very poor, for a crack can easily occur even in the original sample. The cupping value decreases gradually with an increase in pre-strain. The cupping value of TA2 titanium alloy is higher than that of H260 low alloy steel for the constant pre-strain. A quite large difference exists between the two experimental materials. Pre-strain loading pass has no significant effect on the microstructure evolution, mechanical properties, and stamping properties.
