in petrochemical industry, the production of polyvinyl chloride (pvc) is accompanied by formation of heavy end wastes which consist of a mixture of di and multichloro compounds as kind of materials which are generated in ethylene dichloride (edc) purifcation. a high quantity of chloro compounds found in the heavy end waste allows it to be polymerized with alkaline polysulfdes to form polysulfde...
Study of the Mechanical Behaviour of a Zr-Based Metallic Glass Rod Using Micro- and Nano-Indentation
The mechanical properties of a Zr55Cu30Al10Ni5 metallic glass rod are investigated by Vickers microhardness and depth-sensing nanoindentation. The alloy exhibits a relatively large hardness which decreases when increasing the maximum applied load. Serrated flow is also observed during nanoindentation. Both effects are related to deformationinduced mechanical softening.
Introduction:Acidic sludge is a by-product of used motor-oil reprocessing industries which is disposed of in the environment as hazardous waste material. The polymer bitumen under certain conditions is produced from mixing Bentonite soil, polymer styrene - butadiene – styrene(SBS) and acidic sludge.The aim of this study was retrieval of acidic sludge from polymer bitumen using additives such a...
It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...
