High entropy alloys: Probing for structural disorder and magnetic properties

High entropy alloys or HEAs consist of five or more different metallic elements and are an extremely interesting class of materials with a great diversity of potential applications. Since the macroscopic properties of HEAs are strongly dependent on interatomic interactions, researchers can probe their local structure and structural disorder around each individual element by element-specific techniques. Now, a team has utilized unique spectroscopy methods to examine a so-called Cantor alloy—a model system to study the high-entropy effects on the local and macroscopic scales.

One Minute Mentor: Controlled Atmosphere Furnaces

In the past, atmospheric furnaces were used quite often for heat treatment of tool steels. Due to the improved furnace technology of vacuum furnaces and their increased distribution in the market, the percentage of tools heat treated in atmospheric furnaces has fallen significantly over the last 20 to 30 years.

Metal reformation at nanometer scales

Massachusetts Institute of Technology has published a new study that shows what happens when crystalline grains in metals reform at nanometer scales, improving metal properties. This includes recrystallization, in which the metal is deformed and heated.

One Minute Mentor: Salt Bath Furnaces

Molten salts of various compositions are well adapted to all operations in the heat treatment of tool steels. For tools that cannot be ground after hardening or for tools that require an excellent surface condition and the maintenance of sharp edges, salt bath heating provides excellent results.
