Abnormal Nitride Morphologies upon Nitriding Iron-Based Substrates
JOM, 2013Nitriding of iron-based components is a very well-known surface engineering method for bringing about great improvement of the mechanical and chemical properties. An overview is presented of the strikingly different nitride morphologies developing upon nitriding iron-based alloy substrates.

Journal of the American Ceramic Society, 1991
The composition and microstructure of dispersed‐phase ceramic composites containing BN and AIN as well as BN and AIN single‐phase ceramics prepared by chemical vapor deposition have been characterized using X‐ray diffraction, scanning electron microscopy, electron microprobe, and transmission electron microscopy techniques.

Catalysis Propene is one of the highest-volume organic chemicals produced. Propene has mainly been made from naphtha, but changes in the global supply chain are creating shortages. Direct conversion from propane, a component of natural gas, via reaction with oxygen is an attractive alternative, but existing approaches produce a large fraction of ...

Iron nitride/boron nitride magnetic nanocomposite powders
Advanced Materials, 1994A superparamagnetic nanocomposite consisting of magnetic particles in a non‐magnetic matrix phase, FexN/BN (x = 3 or 4), is one result of research targeted at reducing the grain size of crystalline materials from the conventional micrometer to the nanometer range.

Abstract Nitriding is a surface hardening heat treatment that introduces nitrogen into the surface of steel while it is in the ferritic condition. Gas nitriding using ammonia as the nitrogen-carrying species is the most commonly employed process and is emphasized in this chapter.

Creep of silicon nitride-titanium nitride composites
Journal of Materials Science, 1993The effect of particulate TiN additions (0–50 wt%) on creep behaviour of hot-pressed (5 wt%Y2O3 + 2 wt%Al2O3)-doped silicon nitride (HPSN)-based ceramics was studied. Creep was measured using a four-point bending fixture in air at 1100–1340 °C. At 1100 °C, very low creep rates of HPSN with 0–30 wt% TiN are observed at nominal stresses up to 160 MPa. At

Abstract Oxidation usually dominates high-temperature corrosion reactions, but under certain conditions, some alloys may be affected by nitridation as well. This chapter explains why nitridation occurs and how it attacks various metals, in some cases, penetrating deeper than oxidation.
