پژوهش پیشرو در صدد واکاوی و پاسخگویی به این سؤال اساسی بر آمده است که موانع عمدۀ فرهنگی که در دوره پهلوی دوم سبب عدم دستیابی جامعه ایران به توسعه سیاسی گردید، چه بوده است؟ و مهم<...
Abstract In this study, the effect of cooling rate controlled by different castings thickness ranging from 3 to 25 mm on mechanical and corrosion behavior Si–Mo ductile iron (DI) was investigated. SEM-EBSD investigations demonstrated that nodule counts, nodularity, ferrite phase increased while ferritic grain size decreased with decreasing in casting wall thickness; turn led improvements tensil...
Epidamaeus hexatuberculatus sp. n. (Oribatida: Damaeidae) is described from Russia. The new species similar to E. nortoni Bayartogtokh, 2004 and tritylos Behan-Pelletier et Norton, 1983 but differs both by the absence of enantiophyses E2 V, presence mediosejugal enantiophysis, narrowly phylliform interlamellar seta tubercle-like, rounded distally discidium, localization prodorsobasal tubercle Da.
Carbonizing phenomena from carbon-containing mold flux into ultra-low-carbon liquid steel have always been one of the important factors affecting surface quality continuous casting billets. An experimental method has adopted in this investigation to study carbonizing behavior during steel, and locations where occurs process were predicted by ANSYS Fluent numerical simulations. The results indic...
