POINT DEFECTS IN FeAl
Point defects in annealed B2-phase FeAl samples in the range 47-53 at.% Fe were studied using 57Fe Mössbauer spectroscopy. Spectra were analyzed using local environment models according to which point defects in atomic shells close to probe atoms induce shifts in the nuclear monopole interaction. For well-annealed samples, better results were obtained assuming only the presence of FeAl antisite...
متن کاملPhysical metallurgy of nickel aluminides
A description of the important physical metallurgy aspects of Ni3Al and NiAl encompassing structure, crystallographic defects, slip systems and phase stability has been presented in this article. The microstructures generated in the two alloys by conventional as well as novel processing techniques have been discussed. The effect of alloying additions on the microstructure has been enumerated. B...
متن کاملMicrowave embrittlement
Mikrovlnné žiarenie frekvencie 2,45 GHz bolo použité na vzorkách uhlia z rôznych anglických lokalit, na ich tepelnú predúpravu pred rozpojovaním. Získané údaje poukazujú na vplyv mikrovlnnej tepelnej úpravy na relatívnu meliteľnosť uhlia. Výrazná redukcia ( 20 –40 % ) relatívnej energie mletia bola zaznamenaná už po pomerne krátkom čase pôsobenia mikrovlnného žiarenia (3 –8 min). Vplyv mikrovln...
متن کاملGold Embrittlement of Solder Joints
Gold embrittlement of solder joints has been written about for at least four decades [1 – 3]. Nevertheless, gold embrittlement related solder joint failures have been analyzed in this laboratory as recently as July 2009. Gold embrittlement can be avoided by careful solder joint design and knowledge of the causes of this condition. The purpose of this paper is to provide a detailed account of ma...
