  1. 1. Microstructure and Properties of Additively Manufactured Tool Steels for Hot Stamping

    Författare :Miwen Yuan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Wear; Hot stamping; Additive Manufacturing; Softening Resistance;

    Sammanfattning : Hot work tool steels are commonly used to produce dies for hot stamping, where the steels are exposed to cyclic thermal and mechanical loads. There is a constant demand to improve the lifetime of the dies. Additive manufacturing (AM) provides new solutions for tool design. LÄS MER

  3. 2. Hot forming tribology : galling of tools and associated problems

    Författare :Leonardo Pelcastre; Ewald Badisch; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

    Sammanfattning : In recent years, the use of ultra high-strength steels (UHSS) as structural reinforcements and in energy-absorbing systems in automobiles has increased rapidly; mainly in view of their favourable strength to weight ratios. However, due to their high strength, the formability of UHSS is poor, thus complex-shaped UHSS components are invariably produced through hot-metal forming processes. LÄS MER

  4. 3. Modelling and simulation of hot stamping

    Författare :Paul Åkerström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The growing effort to reduce vehicle weight and improve passive safety in the automotive industry has drastically increased the demand for ultra high strength steel components. There are several production technologies for such components. LÄS MER

  5. 4. Self-Lubricating Laser Claddings in the Context of Hot Metal Forming

    Författare :Hector Torres; Braham Prakash; Manuel Rodriquez Ripoll; Paul Mayrhofer; Tomasz Liskiewicz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; High Temperature; Laser Claddings; Self-Lubricating; Hot Stamping; Machine Elements; Maskinelement;

    Sammanfattning : Laser cladding is a coating technique with significant advantages like the high quality of the resulting layers, their excellent metallurgical bonding to the substrate or the possibility to repair/rework high-value mechanical components. In recent years, the incorporation of solid lubricants to the base powder in order to produce self-lubricating claddings has been shown in the literature to be possible, with several of the described coatings being able to operate at high temperatures with low friction and wear.

  7. 5. Concepts for hot sheet metal forming of titanium alloys

    Författare :Eva-Lis Odenberger; Roger Reed; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot sheet metal forming; Titanium; FE simulation; Validation; Springback; HCP; Varmforming; Titan; FE simulering; Validering; Återfjädring; HCP; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER
