1. The role of primary austenite morphology in cast iron
Abstract : Automotive industry products portfolio includes a wide variety of complex-shaped cast iron products, such as truck engine components. Urged by strict environmental regulations on emissions, these components constantly need to combine higher demands on performance with lighter designs. READ MORE

2. 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

3. Biochemical Studies of Semenogelins with Emphasis on Zinc-Binding Properties
Abstract : Semenogelins I and II (SgI and SgII) are homologous and rapidly evolving proteins that have a repetitive primary structure and are synthesized mainly in the seminal vesicles. Upon ejaculation, a gelatinous coagulum is formed when the semenogelin-rich secretion from the seminal vesicles is mixed with the prostate secretion, which contains high concentrations of zinc(II) and proteases.

4. Compacted graphite iron : On solidification phenomena related to shrinkage defects
Abstract : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. READ MORE

5. On the solidification of compacted and spheroidal graphite irons
Abstract : A good understanding of the solidification process of a cast material is essential to understand how the combination of alloy composition and the casting process variables combines into the solid cast component and its performance. The wrong combination may result in poor performance or casting defects. READ MORE
