   Abstract : In the era of urbanization, industrialization and population growth, groundwater and drinking water sources are getting adversely polluted due to the addition of different toxic contaminants including inorganic anionic pollutants. The inorganic anions are of serious concern due to their adverse health effects on humans, even when present at very low concentrations in water. READ MORE

4. 2. On the Origin and Distributions of the Inclusions in Production-scale ESR and PESR Remelted Ingots and Materials from Different Ingot Sizes and Solidification Structures

   Author : Eva Sjöqvist Persson; Pär Jönsson; Torbjörn Carlberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : The study was carried out with the aim to evaluate the origin, morphology, and distribution of the non-metallic inclusions (NMI) in electro-slag remelted (ESR) steels and in electro-slag remelted steels using a pressured controlled inert atmosphere (PESR). In addition to the NMI studies, the solidification structure in different ingot sizes were studied in order to define the influence of the solidification on the NMI characteristics. READ MORE
