9 hours ago · Bearing steel is a type of high carbon chromium steel, typically known for its high hardness and wear resistance. The most common type of bearing steel is AISI 52100, which is a high carbon chromium alloy steel containing around 1% carbon and 1.5% chromium. Additionally, bearing steel may include trace amounts of silicon, manganese, nickel, and molybdenum to further enhance its performance.
9 hours ago · Conventionally used brass alloy CuZn30 shows problems with corrosion resistance in the form of dezincification when used in brass instruments. Therefore, within the scope of this investigation, a new brass alloy CuZn30 is developed in the microalloy range with corrosion-free or corrosion-inhibiting properties. First, the influence of microalloying elements on the phase composition is ...
9 hours ago · The precipitation of secondary Laves phases and its effect on notch sensitivity are systematically studied in Thermo-Span alloy. The results show that the precipitation peak temperature of secondary Laves phases is 925 °C. Below 925 °C, the volume fraction of secondary Laves phases increases with the rise of the temperature, and its morphology changes from granular to thin-film; above 925 ...
9 hours ago · Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer ( passivation) somewhat stabilizes the free metal against further oxidation .
9 hours ago · The global aluminum alloy market was valued at USD 126.5 billion in 2021 and is projected to reach USD 170.5 billion by 2030, growing at a CAGR of 5.1% during the forecast period from 2022 to 2030. This growth is driven by the rapidly expanding automobile and aerospace industries, the booming construction sector, industrial expansion, and the development of land and air transportation.
9 hours ago · Aluminium alloy prices: Aluminium alloy (A356) price and aluminium alloy (A380) price have gained RMB 50 per tonne on July 9 to peg at RMB 20,750 per tonne and RMB 21,100 per tonne, with average prices to range between RMB 20,600-20,900 per tonne and RMB 21,000-21,200 per tonne, respectively.
9 hours ago · Here, an ultramicroelectrodes (UMEs) modification strategy based on bimetallic single-particle was proposed for the first time. This mesoporous platinum/iridium alloy single-particle (mPtIr SP) interface using micelle-assisted electrodeposition was characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).
