  3. 8. On the hot crack formation during solidification of iron-base alloys

    Author : Karin Hansson; KTH; []
    Keywords : hot cracking; hot tearing; cracking fracturing ; tearing; ductility; brittleness; embrittlement; fractures; ductile brittle transition; solidification; iron; copper; nickel; Invar; steels; free machining steels; stainless steels; penetration; crack;

    Abstract : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. READ MORE

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

    Author : Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; 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

  5. 10. Slag inclusion formation during solidification of steel alloys and in cast iron

    Author : Sofia Adolfi; Hasse Fredriksson; Karin Hansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solidification; segregation; precipitation; inclusions; inoculation; EMPA; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : This thesis explores the formation of segregation and inclusions during solidification of steel and cast iron. A better understanding of the formation mechanism should result in decreasing fraction of defects during solidification of ingot and strand material. READ MORE
