2. 1. Mass Transport in Apple Tissue: Effects of Tissue Structure and Osmotic Processing Conditions

   Author : Nikolaos Mavroudis; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; drying; porosity; shrinkage; cell vitality; apple structure; apple; osmotic processing; mass transport; mass transport mechanisms;

   Abstract : Osmotic processing can be a very useful processing step in today’s food industry enabling the production of high quality natural food ingredients out of plant tissues. The maintenance of high product quality is quite product specific with regard to quality attributes. These attributes include fresh/like appearance, taste, texture and composition. READ MORE

4. 2. Factors Influencing the Formation of Shrinkage Porosity in Grey Cast Iron

   Author : Lennart Elmquist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CET; Oxygen; Columnar zone; Grey iron; Shrinkage porosity; Equiaxed zone; Solidification; DAAS; Hydrogen; Primary austenite;

   Abstract : The presence of shrinkage defects is of major concern in the production of grey iron castings. This type of defect can penetrate through the casting as a three-dimensional network. READ MORE

6. 4. Compacted graphite iron : On solidification phenomena related to shrinkage defects

   Author : Björn Domeij; Attila Diószegi; Babette Tonn; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Porosity; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation; porositet;

   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

7. 5. A Study On Factor Influencing the Microstructure and Shrinkage Porosity Formation in Compacted Graphite Iron

   Author : Sadaf Vazehrad; Pär Jönsson; Attila Dioszegi; Steve Dawson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGI; LGI; SGI; Solidification; Microstructure; Shrinkage porosity; Eutectic colony; Microsegregation;

   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
