Static Strain Aging Behavior of Low Carbon Steel Drawn Wire
The static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. Thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. To do so, the wires are austenitized at different temperatures and cooled in different rates. Then the wires are drawn and aged at a specific temperature and time. Before and after aging of each...
متن کاملBiofilm Formation by the Hexavalent Chromium Removing Strain Streptococcus salivarius: in Vitro Approach on Abiotic Surfaces
In this study, a strain of lactic acid bacteria Streptococcus salivarius was studied for its capacity to remove hexavalent chromium (Cr (VI)) from a liquid medium and to form biofilm. Both properties are useful for using the strain in bioremediation of metal-contaminated effluents. For biofilm formation capacity, three methods were used: the tube method (TM), the Congo red agar method (CRA) and...

متن کاملFatigue performance improvement in AISI 4140 steel by dynamic strain aging and dynamic precipitation during warm laser shock peening
Warm laser shock peening (WLSP) is a thermomechanical treatment technique combining the advantages of laser shock peening and dynamic strain aging (DSA). Through DSA, WLSP of steel increases the dislocation density and stabilizes the dislocation structure by pinning of mobile dislocations by carbon atoms. In addition, WLSP generates nanoscale carbide precipitates through strain-induced precipit...
متن کاملRemediation of Chromium-Contaminated Soils Using Pseudomonas aeruginosa Strain BS2
The bioremediation of chromium-contaminated soil by a rhamnolipid biosurfactant produced by Pseudomonas aeruginosa strain BS2 has been explored through column studies using uncontaminated soil spiked with toxic concentrations of heavy metals i.e. 1000 mg/kg chromium. Results on removal of chromium from the spiked soil by using di-rhamnolipid and tap water have shown a high potential of di-rhamn...
