This invention discloses a high-strength, high-ductility, low-density steel and its preparation method. The composition is: C: 0.85–1.15%, Mn: 9.5–12%, Al: 8.5–11.5%, Ni: 2.5–3.5%, Cr: 2–3%, V: 0.3–0.5%, S≤0.005%, P≤0.008%, iron, and unavoidable impurities. The preparation method includes smelting, casting, forging, hot rolling, cold rolling, and recrystallization annealing processes. Through a high-C, medium-Mn, and high-Al synergistic design, Cr suppresses grain boundary carbide segregation, Ni promotes the formation of the B2 ordered phase, and V microalloying promotes the precipitation of the VC precipitate, forming a multi-scale layered structure composed of banded δ-ferrite, equiaxed (Fe,Ni)Al-type B2 phase, austenite, and nano-VC precipitates. The recrystallization annealing process achieves multi-scale layered structure control and synergistic strengthening of equiaxed (Fe,Ni)Al-type B2 phase and VC nanoprecipitates through rapid heating-short holding-rapid cooling. This invention breaks through the bottleneck of balancing strength, plasticity, and density in low-density steel, providing a high-performance material solution for automotive lightweighting.

This invention belongs to the field of additive manufacturing technology, and particularly relates to a filament feeding device and a 3D printer. The device includes a main body with a fixed disk and a rotating turntable. The fixed disk has a drive roller and two straight grooves, while the turntable has two inclined grooves. A sliding block is slidably connected to both the straight and inclined grooves, and a driven roller is mounted on the sliding block. The turntable is connected to a worm gear drive mechanism. The drive roller and the two driven rollers together form a three-point support and clamping structure for the filament. The rotation of the turntable drives the two driven rollers to move radially synchronously, adapting to filaments of different diameters. A ring-shaped PTC heating device is provided at the filament outlet for continuous online drying of the filament. This invention achieves stable filament feeding through a three-point clamping structure, avoiding filament damage and deformation. It also integrates a synchronous drying function, effectively solving the problem of moisture absorption in the printing filament. It has the advantages of stable clamping, strong adaptability, and good drying effect.
