Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy ( martensite - austenite , austenite - ferrite ), known to be associated with strongly enhanced mechanical properties.
A schematic of borocarbonitride (BCN) Borocarbonitrides are two-dimensional compounds that contain boron, nitrogen, and carbon atoms in a ratio BxCyNz. [1] [2] Borocarbonitrides are distinct from B,N co-doped graphene in that the former contains separate boron nitride and graphene domains as well as rings with B-C, B-N, C-N, and C-C bonds. [3]
The MAX phases are layered, hexagonal carbides and nitrides which have the general formula: M n+1 AX n, (MAX) where n = 1 to 4, [1] and M is an early transition metal, A is an A-group (mostly IIIA and IVA, or groups 13 and 14) element and X is either carbon and/or nitrogen.
β-Carbon nitride (beta-carbon nitride), β-C 3 N 4, is a superhard material predicted to be harder than diamond. [ 2 ] The material was first proposed in 1985 by Amy Liu and Marvin L. Cohen .
Manganese nitrides are salts of manganese and the nitride ion. Four of these compounds are stable at atmospheric pressure.The most important is Mn 3 N 2, which catalyzes nitrogen fixation and is a high-temperature antiferromagnet.
Before you whip up a pot of chili, a batch of chimichangas or a pile of sloppy joes, make sure you've got the best chili powder in your spice rack. Our Test Kitchen sampled 10 to find these winners.
Beta carbon nitride - a solid with a formula β-C 3 N 4, which is predicted to be harder than diamond. Graphitic carbon nitride - g-C 3 N 4, with important catalytic and sensor properties. [2] Dicyanodiazomethane (NC) 2 C=N=N, the only C 3 N 4 isomer studied experimentally; Tricyanamide N(CN) 3 - C 3 N 4 monomer (has never been prepared yet)
Hexagonal boron nitride is a ceramic powder lubricant. The most interesting lubricant feature is its high temperature resistance of 1200 °C service temperature in an oxidizing atmosphere. Furthermore, boron nitride has a high thermal conductivity. (Cubic boron nitride is very hard and used as an abrasive and cutting tool component.)
