The stress concentration of In718 superalloy after friction welding and compare with Mar-M247 and In718 welded joints
Friction stir welding (FSW) is a new method that the joining is carried out by friction between two metals and heat creation. The stress concentration phenomena in welded joint cause the stress increasing in welded zone. In this research, modeling and analysis of similar junction of IN718 and Mar-M247 and non-similar junction of IN718-Mar-M247 superalloys were performed by ANSYS Software and fi...

متن کاملEvaluation of Tool Performance With Nanocrystalline Multilayer Coatings on the Machinability of Superalloy Inconel 718
In this paper, the performance of the cutting tool with nanocrystalline multilayer coatings (TiN+TiAlN) for machining of superalloy Inconel 718 in the dry and wet conditions was studied. The multi layer TiN and TiAlN with nanocrystalline structure was applied by physical vapor deposition technique (arc evaporation) on the WC-Co inserts. The results of the ball on disc wear test and the machinin...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
romantic education:reading william wordsworths the prelude in the light of the history of ideas
عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
