Characterization and Morphological Analysis of Pearlite in an Eutectoid Steel
Pearlite is a lamellar product of eutectoid decomposition, which may form in steels and non-ferrous alloys during transformations under isothermal or continuous-cooling (1,2). A pearlite nodule is composed of multiple colonies; each colony has parallel lamellae, which are orientated differently with respect to lamellae in adjacent colonies. This also exhibits a wide range of interlamellar spaci...
متن کاملEffects of Tungsten on the Pearlite Reaction in a Eutectoid Steel
The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...
متن کاملDeveloping Very Fine Nanopearlitic Structure in a High Carbon Steel Wire before Drawing
The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...
متن کاملThe Effect of Interlamellar Distance in Pearlite on CGI Machining
Swedish truck industry is investigating the possibility for implementing the use of Compacted Graphite Iron (CGI) in their heavy duty diesel engines. Compared to the alloyed gray iron used today, CGI has superior mechanical properties but not as good machinability. Another issue that needs to be addressed when implementing CGI is the inhomogeneous microstructure when the cast component has diff...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
