16. Morphological characterization of primary austenite in cast iron
Abstract : Automotive industry products portfolio includes a wide variety of complex‐shaped cast iron products, such as truck engine components, that need to withstand a constant trend of higher demands, especially urged by stricter environmental regulations on emissions. Combined with this continued demand on properties improvement, cast iron industry faces a process problem related to the lack of understanding of solidification and mechanisms behind defect formation.

17. A Study On Factor Influencing the Microstructure and Shrinkage Porosity Formation in Compacted Graphite Iron
Abstract : During the last decades, an intensive effort has been dedicated to introduce compacted graphite iron (CGI) for truck engine components as its intermediate graphite morphology provides an increased tensile property compared to lamellar cast iron (LGI) and a better thermal conductivity compared to nodular cast iron (SGI). However, the narrow production technology window in this cast iron grade requires increased technological discipline. READ MORE

18. Characterization and Modification of Microstructure in Al-Co-Cr-Fe-Ni Eutectic High-Entropy Alloys
Abstract : The recently emerging high-entropy alloys (HEAs) present a novel alloying strategy, significantly expanding the scope of metal alloy design. HEAs are defined as alloys consisting of at least four principal elements in equi- or near equiatomic ratios, with a possibility of small amounts of alloying elements. READ MORE

19. An Experimental Study of Liquid Steel Sampling
Abstract : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. READ MORE

20. On the Study of a Liquid Steel Sampling Process
Abstract : The liquid steel sampling method is one of the commonly used procedures in monitoring the steelmaking process. Besides it can be used for analyzing the dissolved alloys, hydrogen content and oxygen content, it can be also employed to monitor the inclusion characteristics at the steelmakings. READ MORE
