  5. 3. Closed-die forging and slab hot rolling with focus on material yield : some industrial problems analysed by FEM

    Author : Esa Ervasti; Ulf Ståhlberg; Hans Keife; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material yield; Closed-die forging; Hot rolling; Cracks; Macro-inclusions; Steel; FEM; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : The thesis is focussed on improving the material yield in closed-die forging and rolling. The former is restricted to the manufacturing of heavy crown wheels and front axle beams and the latter to the hot rolling of steel slabs. To enhance the yield the commercial FE-codes Form2D and Dyna3D are used. READ MORE

  7. 5. Chromium martensitic hot-work tool steels : damage, performance and microstructure

    Author : Johnny Sjöström; Jens Bergström; Farhad Rezai-Aria; Karlstads universitet; []
    Keywords : Hot-work tool steel; thermal fatigue; microstructure; Materialteknik; Materials Engineering;

    Abstract : Chromium martensitic hot-work tool steel (AISI H13) is commonly used as die material in hot forming techniques such as die casting, hot rolling, extrusion and hot forging. They are developed to endure the severe conditions by high mechanical properties attained by a complex microstructure. READ MORE
