In this paper, the relationship between anisotropic mechanical properties and corresponding microstructure evolution of wrought magnesium alloys is critically reviewed. Experimental observations strong anisotropy (including strength differential effect) induced by texture twinning are discussed under different loading conditions (i.e., monotonic, cyclic multiaxial loading). An accurate constitutive model essential to describe responses predict forming performance considering engineering...
Abstract At low temperatures most metals show reduced ductility and impact toughness. Here, we report a compositionally lean, fine-grained Fe-30Mn-0.11C austenitic steel that breaks this rule, exhibiting an increase in strength, elongation Charpy toughness with decreasing temperature. A energy of 453 J is achieved at liquid nitrogen temperatures, which about four to five times conventional cryogenic steels. The high attributed manganese carbon austenite stabilizing elements, coupled...
Abstract The stable operation of strip rolling mill is the key factor to ensure stability product quality. design capability existing domestic imported and self-developed mills cannot be fully developed, frequent occurrence vibration instability problems seriously restrict equipment capacity production high-end products. prediction analysis method for hot based on eXtreme gradient boosting (XGBoost) Bayesian optimization (BO) proposed. First, an XGBoost model developed a self-built data set...
Polyimide cross-linked silica gels with different weight percentages of solid precursors and volumes MTMS were prepared by using bis(trimethoxysilylpropyl)amine (BTMSPA) polyamide acid, synthesized 4,4′-oxydianiline (ODA), p-phenylenediamine (PPDA) biphenyl-3,3′,4,4′-tetracarboxylic dianhydride (BPDA), compounding a network which was hydrolysed MTMS, then supercritically dried to produce hybrid aerogel. The obtained aerogels exhibit striking properties such as low density (as 90 mg cm−3),...
DRX (dynamic recrystallization) behavior, which can improve the product's microstructure and enhance its performance, is vital in high-temperature plastic deformation of metal materials. In this paper, single-pass hot compression tests were carried out on a Gleeble-3800 thermo-mechanical simulator to investigate behavior low carbon steel at temperature 900°C–1100 °C strain rate 0.01s−1-0.1s−1. The effect was investigated based direct connection between dynamic softening behavior....
The main load-bearing structure of submarines is the pressure shell. Shell failures are usually caused by high hydrostatic and its own potential geometric imperfections. This paper proposes a cylindrical shell with strong corrugated stiffening structure. Two theoretically geometrically identical shells fabricated using CNC machining to ensure reproducibility reasonableness results. Firstly, point cloud data all parameters were obtained 3D scanner. Geomagic Control X inspection software was...
Martensitic transformation can easily induce a maximum hardness value of 800–900 HV (Vickers hardness) for steels with carbon contents 0.6 wt.% and above. However, the occurrence martensitic in pure iron requires exceptionally high cooling rates (105–106°C/s), achievable is only about 150 HV. Here we report an extreme 830 obtained through pressure induced at rather slow rate just 10°C/s. This unprecedented strength originates from formation twin-related laths average thickness 3.8 nm.
