Introduction, large iron atoms, and thus to forge both sword and ploughshare (and so his destiny). However, only in recent decades has the scope of interstitial alloys multiplied so greatly and in so many novel directions, because only now has the real demand arisen in science and industry. Moreover, most of the采纳 发表于 2025-3-23 15:17:09
Metal Physics of Interstitial Alloys,he atomic diameter for all elements in the manner of concentric circles*; the periods of the Periodic Table are allotted different sectors. This shows the relative dimensions as well as the variations with atomic number, group and period. For our purpose, the diagram indicates the elemental combinat火车车轮 发表于 2025-3-23 21:53:04

Nitrides,hardness in the early Groups) and in their fields of practical application. Also their stability and occurrence within the frame of the Periodic System is similar to those of the carbides. There are, however, important differences, largely bound up with the trivalency of the nitrogen atom against quColonnade 发表于 2025-3-24 02:28:51

Silicides, position, intermediate to interstitial and intermetallic compounds. Nevertheless, their inclusion here is justified on several grounds. Firstly, there is their close relationship to the borides (Chapter 6), structurally, in properties and in areas of application. Also silicon still . form genuine iObstruction 发表于 2025-3-24 11:20:34

Hydrides, of all. Its small size is not much larger than the naturally occurring interstices in the host transition-metal lattice, and these can usually accommodate the hydrogen atom or ion to extensive degrees with less strain on the metal lattice than for say C, N or O. Hägg’s rule is always fulfilled. WheCatheter 发表于 2025-3-24 19:38:24
Mixed Interstitial Compounds,pters, we now consider their combinations. The number of interstitial compounds and solution series possible by mutual combinations is clearly enormous. It is only intended here, however, to bring out some points of principle and to give typical examples demonstrating trends. A systematic treatment无法取消 发表于 2025-3-25 02:56:05
