the effects of carbon content on the dynamic and static softening mechanisms of ti microalloy steels were investigated both in ferrite and austenite regions. the results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. this is due to the ti(cn) and tic precipitates and also the free carbon content. in the ferrite regio...

Weldability of high carbon steels due to the high percentage of carbon and consequently formation of martensitic structure is very poor. In this research, resistance spot welding of eutectoid high carbon steel 1075 is experimentally and numerically investigated from various points of view. The effect of welding current as one of the most effective parameters on failure mode, mechanical properti...

Abstract Background: Today, vermicompost production process as one of the very good procedures in terms of economic,health, and environmental sustainability to stabilize the organic waste is discussed. The aim of this study is vermicompost production from urban waste by earthworm (Eisenia Fetida) in Household-scale. Methods: In this experimental study, plastic tank of vermicompost product...
As the global pursuit of carbon neutrality has intensified, influence emission limits on supply chain become increasingly evident. The purpose this study is to investigate optimal financing options under reduction percentage measure and provide recommendations for carbon-emitting enterprises. This focuses a consisting capital-constrained manufacturer capital-rich retailer. Under measure, we use...
co2 is the main greenhouse gas which urban forests have a high potential to absorb and sequestrate it. the air pollution of tehran is one of the most important environmental problems of the iran. to do this research 40 years old stands of robinia pseudoacacia and fraxinus rotundifolia and the surrounding barren land ( as blank) were selected in chitgar forest park of tehran and the amount of ca...
