Inclusions in primary aluminium were analysed with an electron-probe microanalyser and a high-resolution Auger electron spectrometer. In multiphase eutectic and complex inclusions the presence of ...calcium, magnesium, iron, copper, molybdenum and aluminium was detected. Prior to Auger analysis, sufficient ion etching is necessary for the elimination of oxides from the surface. The complex inclusions, with calcium content, reacted with water which demanded the choice of a suitable technique for the preparation of metallographic samples.
Istraživala se je morfologija i fazna struktura tankih dvoslojeva Ag/PbTe. Taj je sustav posebno zanimljiv zbog graničnih reakcija koje su se ranije opazile u sličnom sustavu Ag/SnTe. Odredili su se ...reakcijski produkti koji nastaju uzajamnom difuzijom Ag i podloge kao i njihove orijentacije, te raspravljaju strukturni odnosi s PbTe.
