The objective of this study is to characterise grade R4 steel manufactured by ingot casting that used as the raw material for production offshore mooring chains. Rolled bars have been selected and metallographic analyses micro hardness, tensile Charpy V-notch impact tests performed. Tensile also carried out on links from same steel. Based results presented, influence rolling reduction ratio coo...

A titanium–iron intermetallic with minor addition of manganese (TiFe0.7Mn0.3) was processed by severe plastic deformation through high-pressure sliding (HPS). rectangular strip sample embedded in stainless steel and strained under a pressure 4 GPa at room temperature. The hydrogen storage kinetics activation the HPS-processed were significantly enhanced comparison as-received ingot without HPS ...

In order to lower fuel consumption and reduce emissions, aluminum is being considered as an alternative to steel in large scale production of autobodies. This study evaluates the prospects of aluminum sheets as a cost efficient alternative to steel in autobodies with the unibody design. The study focuses on the processing technologies and alloy selection for aluminum automotive sheets and looks...

          USD7 is one of the steel products of Isfahan Steel Company. It is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. Finally, it is wire drawn up to 3 mm and used as welding electrodes. This steel contains 0.05 to 0.09 wt. % carbon. The acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. Therefore, it is categorized as rimmed steel...
