Radiological characterization of Cayirhan coal-fired power plant in Turkey
(Elsevier Sci Ltd, 2007)
Natural radioactivity of Cayirhan lignite coal treated at Cayirhan (Ankara, Turkey) power plant, its ash and soil samples mixed with ash in the power plant field were investigated. For comparison, soil samples were collected ...
Temperature dependence of ZnO rods produced by ultrasonic spray pyrolysis method
(Elsevier Science Sa, 2007)
Zinc oxide (ZnO) microrods were prepared at different substrate temperatures by ultrasonic spray pyrolysis technique on glass substrates. The X-ray diffraction patterns show that obtained rods are composed of wurtzite-type ...
Some aspects of thermally induced martensite in Fe-30% Ni-5% Cu alloy
(Elsevier Science Bv, 2007)
Kinetical, morphological, crystallographical and several thermal properties of thermally induced martensite in the austenite phase of Fe-30% Ni-5% Cu alloy were investigated. Scanning electron microscope (SEM), transmission ...
Martensitic transformation and magnetic properties of Fe-24.5%Ni-4.5%Si alloy
(Maney Publishing, 2007)
The effect of austenitising temperature and cooling rate on the morphology and magnetic properties of martensite in Fe-24-5%Ni-4-5%Si alloy has been studied by means of scanning electron microscopy, Mbssbauer spectroscopy ...
Effect of austenitization heat treatment on the magnetic properties of Fe-40wt% Ni-2wt% Mn alloy
(Journal Of Univ Of Science And Technology Beijing, 2007)
The effect of austenitization heat treatment on magnetic properties was examined by means of Mossbauer spectroscopy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was obtained by using scanning electron microscopy ...
