Anatase-to-rutile phase transformation was studied in milled and unmilled samples. Ball milling was carried out in two types of ball mills, planetary and tumbler, with a ball-to-powder ratio of 40:1 over 2-48 hours. First, the unmilled samples were heated in the furnace at various temperatures for different periods of time. The results revealed that the anatase-to-rutile transformation comple...

plant tissue culture techniques are used as basic requirement of common plant transformation systems. in most cases of plant transformation, a reproducible regeneration protocol is the limiting step due to long time lasting, specialized facilities and well experienced persons. furthermore, tissue culture procedures induce somaclonal variation among regenerated transgenic plants. therefore, rece...

This article evaluates the effect of recrystallization annealing soaking time on tribological behavior cold upsetted low carbon steel. The 40% formed steel was subjected to at 900 °C, for 10, 20, 30, 40, 50 and 60 minutes. mechanical properties hardness, tensile strength, yield strength ductility, measured through specific deformation, as well precipitation carbides microstructural analysis wer...
