mena3100,Emnet gir en innføring i sentrale materialkarakteriseringsmetoder knyttet til bestemmelse av materialers struktur, sammensetning og fasestabilitet. Metodene du vil bli kjent med inkluderer bla. termisk analyse (TA), lysmikroskopi (LM), skanning- og transmisjonselektronmikroskopi . Tingnan ang higit paEtter å ha fullført dette emnet skal du kunne: 1. forstå og beskrive de grunnleggende prinsippene bak de karakteriseringsmetodene .

Can use peak areas or peak-to-background ratios. Auger spectrum - quantification. Concentration of element NA is: NA = IA/(IA + FABIB+FACIC+..) I is the element intensity. F is a sensitivity factor determined from binary standards such that: FAB = (IA/NA/IB/NB) This is highly simplified but can work reasonable well.

Presentation Transcript. Electron diffraction Selected area diffraction (SAD) in TEM Electron back scatter diffraction (EBSD) in SEM MENA3100. Bragg’s law Bragg’s law tells you at which angle θB to expect maximum diffracted intensity for a particular family of crystal planes. For large crystals, all other angles give zero intensity.
