Invited review: Carbides and nitrides in steel
D.H. Jack,K.H. Jack +1 more
TL;DR: In this paper, the crystal chemistry and the occurrence of carbides and nitrides in steels are reviewed and the characteristics of nitrogen are emphasised and are related to the behaviour of carbon.
Book
Ultra-High Temperature Materials III: Refractory Carbides II (Ti and V Carbides)
TL;DR: In this article, the authors provide a thorough treatment of ultra-high temperature materials with melting (sublimation or decomposition) points around or over 2500 °C, including binary, ternary and multi-component systems.
Book
Ultra-High Temperature Materials II: Refractory Carbides I (Ta, Hf, NB and Zr Carbides)
TL;DR: In this paper, a thorough treatment of ultra-high temperature materials with melting points around or over 2500 °C is presented, which can be applied in various engineering devices and environmental conditions in the wide range from cryogenic to ultra high temperatures, on the basis of the latest updates in the field of physics, chemistry, nanotechnology, materials science and engineering.
Journal ArticleDOI
Nitrogen ordering and ferromagnetic properties of ϵ-Fe3N1+x (0.10≤x≤0.39) and ϵ-Fe3(N0.80C0.20)1.38
TL;DR: In this paper, the type and degree of occupational order of N and N+C, respectively, were determined as a function of composition and temperature, and the ordering of N is closely related to that of the ϵ-Fe3N ‘ideal’ structure (space group P6322).
Journal ArticleDOI
The niobium-carbon system
TL;DR: A critical review of the available phase equilibria, crystallographic, and thermodynamic data for the niobium-carbon system is presented in this article, where the existence of two carbides is well established; both have appreciable ranges of homogeneity.

X-Ray Diffraction in Crystals, Imperfect Crystals, and Amorphous Bodies
TL;DR: In the formalism of Newman-Penrose, a family of exact solutions of the Einsteirr-Maxwell equations of the type of Bertotti-Robinson is obtained with a cosmological term belonging to the degenerate type D in the algebraic classification of Petrov.
