The modeling and control of a two-wheeled inverted pendulum (TWIP) is gaining much interest due to the various advancements in hardware computing technologies. A TWIP system has many advantages applications. However, it still faces challenges such as positioning, disturbance rejection, parameter uncertainties, etc. In this paper, scheme based on modern techniques presented overcome these issues...

High-manganese twinning-induced plasticity (TWIP) steels exhibit high strain hardening, tensile strength, and ductility, which make them attractive for structural applications. At low rates, TWIP are prone to hydrogen embrittlement (HE). Here though, we study the hardening strengthening resulting from electrochemical hydrogen-charging of a surface layer Fe-26.9Mn-0.28C (wt.%) steel. We observed...

High- and medium-entropy alloys (HEAs MEAs) possess high solid-solution strength. Numerous investigations have been conducted on its impact yield strength, however, there are limited reports regarding the relation between strengthening strain-hardening rate. In addition, no attempt has made to account for dislocation-mediated plasticity; most works focused twinning- or transformation-induced pl...

This study demonstrates transformation-induced plasticity (TRIP) in conjunction with twinning-induced (TWIP) α + β titanium alloys by introducing metastable retained β-phase. By annealing at 850 °C followed water quenching, β-phase (∼25%) was obtained Ti–6Al–4V alloy. Stress-induced phase transformation the produced orthorhombic α′′-martensite associated (021)α′′ twinning, which significantly i...

In this study, based on the sensitivity of chemical composition fluctuation to thermodynamic parameter, which controls level stacking fault energy (SFE), a series high Cr–Mn–N twinning-induced plasticity (TWIP) stainless steels are designed by using sublattice model, and their mechanical properties micro deformation mechanism analyzed The formation twins (Mts) during makes test steel show perfe...
