Researchers in China have summarized two decades of phase engineering work to see how regulating the rearrangements of materials may enable sustainable energy conversion processes, with a specific focus on electrocatalysts, including how the field might progress.
A team at the Research Institute for Electronic Science at Hokkaido University, Japan, has synthesized a barium cobalt oxide thermoelectric converter that is reproducibly stable and efficient at temperatures as high as 600°C, opening new avenues towards the widespread use of thermoelectric converters.
Video description This video from Ekeeda explains the carbonitriding process for ferrous alloys. Carbonitriding increases the surface hardness of metals thereby reducing wear.
Video description An overview of shape memory materials and their applications, with a detailed look at the Dynalloy Space Wings II and other research performed as part of the University of Michigan’s SURE Program.
Austenitizing is the most critical of all heating operations performed on tool steels. Along with quenching it will usually be referred to as the hardening step in tool steel heat treatment and, associated with tempering, will be responsible for the final properties.
