  1. 1. Fatigue Assessment of Cast Components : Influence of Cast Defects

    Author : Anders Björkblad; Jack Samuelsson; Gary Marquis; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cast nodular iron; fatigue; design rules; fracture mechanics; Vehicle engineering; Farkostteknik;

    Abstract :  This thesis is on the fatigue assessment of cast components with special attention to defects. The primary material in view is nodular cast iron, but also cast steel is considered. However, the fatigue behaviour is in principle valid for general use on other cast metals. READ MORE

  2. 2. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

    Author : Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Chalmers University of Technology; []
    Keywords : Solidification; Solid state transformation; Modelling; Mechanical properties; Cast iron; CGI; Microstructure formation; Cast Iron; Microstructure Formation; Mechanical Properties; Solid State Transformation;

    Abstract : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. READ MORE

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

    Author : Björn Domeij; Attila Diószegi; Babette Tonn; Högskolan i Jönköping; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 4. Crack Initiation in Nodular cast Iron

    Author : Marie Mörtsell; Chalmers University of Technology; []
    Keywords : nodualr cast iron; fatigue; mechanical properties; crack initiation;

    Abstract : .... READ MORE

  5. 5. High Temperature Corrosion of Cast Irons and Steels

    Author : Frédéric Tholence; Chalmers University of Technology; []
    Keywords : high temperature corrosion; cast steel; austenitic stainless steel; SiMo; cast iron; oxidation; exhaust gases; Ni-resist; LCF; ferritic stainless steel;

    Abstract : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. READ MORE
