  2. 1. Toughness of Tool Steel

    Author : Henrik Jesperson; Håkan Engqvist; Birger Karlsson; Uppsala universitet; []
    Keywords : Toughness; Tool Steel; Heat Treatment; Temperature; Energy absorption; Impact Testing; Fracture Toughness Testing; Non-metallic Inclusions; Carbides; Nitrides; Statistics; TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Toughness is the ability to resist tensile stresses in the presence of a notch or crack. Sometimes gross cracking of industrial tools, mould or dies, occurs due to insufficient toughness. As the economic consequences of the gross cracking are serious, the toughness of industrial tool material, generally tool steel, is of paramount importance. READ MORE

  6. 4. Plastic Deformation of Duplex Stainless Steel

    Author : Magnus Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Abstract : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. READ MORE

  7. 5. Fracture toughness properties of duplex stainless steels

    Author : Henrik Sieurin; Rolf Sandström; Jan-Olof Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; fracture toughness; austenite reformation; sigma phase; material optimisation; Materials science; Teknisk materialvetenskap;

    Abstract : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. READ MORE
