In high-speed steel, carbides are essential phase constituents, which have a direct impact on engineering performance and qualities of steel. The formation, morphology, distribution dictated by alloying elements. this paper, various types in steel presented. effects different elements such as C, W, Mo, Cr, V the formation discussed. Research progresses carbide improvement microalloying N, B, Mg, rare earth (RE) reviewed. It is reported that Cr promotes precipitation M2C, N enhances fibrous...
Bacteria-infected wound healing has attracted widespread attention in biomedical engineering. Wound dressing is a potential strategy for repairing infectious wounds. However, the development of with appropriate physiochemical, antibacterial, and hemostatic properties, remains challenging. Hence, there motivation to develop new synthetic dressings improve bacteria-infected healing. Here, we fabricate biocompatible sponge through covalent crosslinking collagen (Col), quaternized chitosan...
Infectious bone defects resulting from surgery, infection, or trauma are a prevalent clinical issue. Current treatments commonly used include systemic antibiotics and autografts allografts. Nevertheless, therapies come with various disadvantages, including multidrug-resistant bacteria, complications arising the donor site, immune rejection, which makes artificial implants desirable. However, can fail due to bacterial infections inadequate fusion after implantation. Thus, development of...
Hot tearing is a serious destructive solidification defect of magnesium alloys and other casting metals. Quantitative controllable measurements on the thermal mechanical behavior an alloy during its process are crucial for understanding hot formation. We developed new experimental method setup to characterize via controlled cooling active loading force hearing formation at selected fractions solid. The was fully instrumented so that stress, strain, strain rate, temperature can be measured...
A NbTiHfZr high-entropy alloy (HEA) with a main phase of body-centered cubic structure is fabricated. Some hexagonal closed-packed (hcp) precipitates are observed in this alloy. thermal-mechanical process, i.e., cold-rolling followed by annealing, can manipulate the volume fraction hcp nano-precipitates that enhance strength and ductility. The enhancement tailorable as function nano-precipitate. results indicate strength-ductility property be manipulated via adjusting post-deformation...
The combustion characteristics of both pure propane hydrates and the mixtures quartz sands were investigated by experiments. flame propagation, appearance, burning time temperature in different hydrate layers studied. For combustion, initial falls “premixed” category. propagates very rapidly, mainly as a result burnt gas expansion. finally self-extinguishes with some proportion remaining unburned. hydrate-sand mixture takes form many tiny discontinuous flames appearing disappearing at...
Abstract Metal casting is an important manufacturing technology for efficiently producing massive components with complex shape. A large share of industrial castings made from iron and steel alloys, combining attractive properties low production cost. Upgrading in cast mainly achieved by alloying fewer cases heat treatment. Molybdenum element that respect, increasing strength, hardness toughness. It also facilitates particular treatments such as austempering. The paper describes the...
Wireless sensing is capable of capturing rich information human target without requiring sensors attached to the target. Although promising, two critical issues still exist, i.e., (i) limited range, and (ii) severe interference in real-world settings. Recently, LoRa employed improve range. able achieve a longer range than WiFi acoustic sensing, it tens meters. In this paper, we propose ChirpSen, which fully exploits property chirp signal increase ChirpSen adopts concentration scheme...
Precipitation strengthening is a crucial method for enhancing the mechanical properties of steel. The bridgman directional solidification furnace, optical microscope (OM), scanning electron (SEM), probe analyzer (EPMA) and transmission (TEM) were used to investigate effect cooling rate on microstructure, microsegregation, nanoprecipitates in medium carbon CrMo cast results indicate that as increases, microstructure significantly refined. relationship between (CA) primary dendrite arm spacing...
While numerous hydrogel dressings are available for treating chronically infected wounds, their clinical application is impeded by intricate preparation processes, low mechanical strength, and frequent reliance on exogenous antimicrobial agents. The latter often leads to antibiotic misuse compromises the bioactivity of cell growth-promoting substances. Therefore, field therapeutic treatment faced with a pressing need prepare high-mechanical-strength hydrogels through facile procedure,...
