  2. 6. Rapid solidification behaviour of Fe and Al based alloys

    Author : Sathees Ranganathan; Hasse Fredriksson; Zhongyun Fan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid solidification; Melt spinning; Metastable phases; Fe based alloys.; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s). READ MORE

  7. 10. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns : the formation of piezoelectric beta-phase crystallinity

    Author : Anja Lund; Högskolan i Borås; []
    Keywords : fibres; PVDF; Textilteknologi;

    Abstract : The present study investigates the possibilities of manufacturing piezoelectric polymer fibres or yarns for integration into textile materials. The polymers known to give the strongest piezoelectric effects are poly(vinylidene fluoride) (PVDF) and some of its copolymers. READ MORE
