Abstract: Provided are a high-plasticity dual-phase high-entropy alloy (HEA) and a preparation method thereof. The high-plasticity dual-phase HEA has a chemical formula as shown in Formula I: (FeCoNiCr)100-xTix (Formula I), in which, x is in a range of 2.0 to 2.8. A method for preparing the high-plasticity dual-phase HEA is also provided.

Abstract: The present disclosure provides a high-entropy alloy (HEA) with room-temperature superplasticity and a preparation method thereof, belonging to the field of metal materials. In the present disclosure, the HEA with room-temperature superplasticity has a chemical formula shown in Formula I: (FeCoNiCr)100-xCux (Formula I), where in Formula I, x is 2.0 to 4.0. A FeCoNiCr alloy is used as a matrix, and then added with a trace amount of a Cu element, thereby significantly reducing formation of a metastable phase in the FeCoNiCr alloy while reducing stacking fault energy of the alloy, such that the alloy maintains a desirable work hardening ability and achieves an excellent elongation at break. Moreover, a plasticity of the alloy is further improved through twinning-induced plasticity (TWIP).

Abstract: An organic glass includes an acrylic plate, a methyl methacrylate layer, and a fluorescent bubble layer that are sequentially stacked; and the fluorescent bubble layer is prepared from fluorescent polymethyl methacrylate beads, a first methyl methacrylate prepolymer and a second methyl methacrylate prepolymer. The fluorescent polymethyl methacrylate beads added into the raw material of the organic glass have an expandable characteristic, and can generate bubbles according to a design pattern to achieve the purpose of controllable bubbles, and the added fluorescent polymethyl methacrylate beads show fluorescent green under ultraviolet irradiation, giving bubbles a fluorescent color, and enabling the organic glass to have extremely artistic and decorative effects.

Abstract: The present invention discloses a preparation method for a surface molding film of a PVC-based stone plastic composite board, including: surface activation treatment of the PVC-based stone plastic composite board: preparation of an activated putty, coarse roughening of a substrate surface, application and solidification of the activated putty, and fine roughening of the substrate surface; preparation of a PMMA slurry; and surface film forming of the PVC-based stone plastic composite board. The PVC-based stone plastic composite board coated with a PMMA film is obtained by cold pressing and shaping in a mold, tightening up a clamp, solidifying at low temperature, treating at high temperature, cooling and demolding.

Abstract: Some embodiments of the disclosure provide a toughened TiAl-based alloy sheet with periodically misaligned through-hole titanium alloy layers sequentially stacked together. A through structure is formed in the misaligned through-hole titanium alloy layer. Two openings of the through structure are respectively located on upper and lower surfaces of the titanium alloy layer. The misaligned opening position of the through structure is at a center position of a quadrangle formed by every four through holes in adjacent titanium alloy layers. The through structure is filled with a TiAl-based alloy. The TiAl-based alloy layers on adjacent sides of the titanium alloy layer are connected through the TiAl-based alloy in the through structure. The TiAl-based alloy layer is connected to the titanium alloy layer through a Ti3Al interface layer. The TiAl-based alloy and the titanium alloy in the through structure are connected through a Ti3Al interface layer.
