Various in-situ methods can track realtime heat treatment response in bulk materials. This can aid material engineers in designing the most effective heat treatment procedures and processing methods. In-situ methods such as thermogravimetry (TG), differential thermal analysis (DTA), and dilatometry, offer capabilities to examine heat treatment behavior in real time, giving insight into the thermochemical mechanisms and the thermal behavior of steel.
With government mandates to reduce greenhouse gas (GHG) emissions, decarbonizing the largest industrial emitters has become an essential research focus. The Environmental Protection Agency (EPA) reported that industrial point sources in the United States (U.S.) emitted 1.45 billion tons of carbon dioxide (CO2) in 2022, accounting for 23 percent of all domestic CO2 emissions for that year (Refs. 1,2). One of the largest contributors to industrial emissions is the iron and steel industry, which was responsible for 2.5 percent of total U.S. GHG emissions in 2023 (Ref. 3). Due to the large quantity of emissions available for capture from this industrial sector, iron/steel production facilities present an impactful opportunity for industrial decarbonization.
TCI Precision Metals has introduced custom-cut, ready-to-ship blanks. Customers can now order custom-sized, pre-machined materials that ship fast and arrive ready to go directly from receiving to finish machining.
In this paper, ultrasonic fatigue testing results for “core hardened” AMS 6308 gear steel are presented. AMS 6308 is a gear and bearing steel with high tempering resistance and high hot hardness case targeted to high temperature applications
Gears serve as essential mechanisms in a wide range of mechanical equipment, helping to transmit torque, adjust rotational speeds, transfer power, distribute load and more. Used in necessary applications such as automobiles, energy systems, aerospace and industrial equipment, gears must be able to operate for long periods without maintenance. While gears can be made from a diverse assortment of materials, carbon and alloy steel offer superior benefits in terms of strength, durability and cost efficiency. As a remarkably recyclable material, steel may also be a preferable choice for environmentally conscious manufacturers.
TCI Precision Metals will be showing its precision Machine-Ready Blanks capabilities to customers at IMTS 2022, McCormick Place, Chicago, IL, September 12-17, 2022, West Building, Booth #432123.
Standardized methods, like AGMA 2001-D04 or ISO 6336 for the calculation of the load carrying capacities of gears are intentionally conservative to ensure broad applicability in industrial practice. However, new applications and higher requirements often demand more detailed design calculations nowadays; for example: long operating lives in wind power gearboxes or fewer gear stages and higher speeds in e-mobility applications result in higher load cycles per tooth in a gearbox.
