摘要: Methods of manufacturing multi-material fibers having one or more electrically-connectable devices disposed therein are described. In certain instances, the methods include the steps of: positioning the electrically-connectable device(s) within a corresponding pocket provided in a preform material; positioning a first electrical conductor longitudinally within a first conduit provided in the preform material; and drawing the multi-material fiber by causing the preform material to flow, such that the first electrical conductor extends within the multi-material fiber along a longitudinal axis thereof and makes an electrical contact with a first electrode located on each electrically-connectable device. A metallurgical bond may be formed between the first electrical conductor and the first electrode while drawing the multi-material fiber and/or, after drawing the multi-material fiber, the first electrical conductor may be located substantially along a neutral axis of the multi-material fiber.

摘要: The present disclosure relates to a hot working method for stainless steel bars, comprising: step (1) heating a steel ingot at a heating temperature in a range from 1200 °C to 1270 °C; step (2) subjecting the heated steel ingot to radial forging and cogging down according to a total compression ratio greater than 3 to obtain a square billet; step (3) heating the square billet at a heating temperature in a range from 1200 °C to 1270 °C; and step (4) subjecting the heated square billet to hot rolling to obtain a bar. The processing method of the present disclosure can avoid the quality defect of surface crack while ensuring production efficiency by optimizing the process flow and controlling key process parameters, so that niobium-containing high-alloy austenitic heat-resistant stainless steel bars with good surface quality and structure can be prepared.

摘要: The disclosure relates to the technical field of preparing the metal material of magnesium alloy, and particularly provides a method for preparing biomedical magnesium alloy wires. The magnesium, zinc, and neodymium alloys are subject to smelting, casting, rolling, and other processes to prepare plates. The plates are subjected to a special mechanical stirring process to prepare a processing zone with the same thickness as the plates. After machining, the processing zone is used as the final product of the wire or drawn in multiple passes to finally form the wire with the required diameter. By introducing rolling and mechanical stirring processes, the disclosure improves the forming property of the wire, so that the alloy grains are significantly refined, the size of the second phase is greatly reduced and most of them are solid-soluble in the matrix, the strength of the obtained wire, and especially the elongation, is greatly improved, and better corrosion resistance is obtained, which meet the performance requirements of medical magnesium alloy wire.

摘要: A spring steel having a superior fatigue life, and a manufacturing method for the same. The chemical components thereof are as follows in weight percentage: C: 0.52-0.62%, Si: 1.20-1.45%, Mn: 0.25-0.75%, Cr: 0.30-0.80%, V: 0.01-0.15%, Nb: 0.001-0.05%, N: 0.001-0.009%, O: 0.0005-0.0040%, P: ≤ 0.015%, S: ≤ 0.015%, and Al: ≤ 0.0045%, with the remainder being Fe and incidental impurities, wherein the following condition is also met 0.02 ≤ (2Nb+V)/(20N+C) ≤ 0.40. The spring steel of the present invention has a microstructure of tempered troostite + tempered sorbite, a prior austenite grain size less than 80 um, a size of alloy nitride and carbide precipitates being 5-60 nm, and a maximum width of single-grain inclusions being less than 30 µm. The spring steel has a handling strength greater than 2020 MPa, superior ductility and toughness (the reduction of area ≥ 40%), and a fatigue life ≥ 800,000 times, thereby meeting application requirements of high-stress springs in industries, such as automobiles, machinery, and the like.
