  1. 1. 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

  3. 2. Material characterisation for analyses of titanium sheet metal forming

    Författare :Eva-Lis Odenberger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : New demands and opportunities for simulation driven product development, that today's finite element (FE) technology allow for, exists in modern industry. Full applicability, in which decisions based on numerical evaluations and predictions, require accurate material parameters and of course accurate modelling of remaining features. LÄS MER

  4. 3. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys

    Författare :Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Juan Carlos Cante Teran; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloy 718; Haynes 282; cold forming; hot forming; material characterization; GISSMO; welding; heat treatment; manufacturing chain; springback; shape distortions; dynamic strain aging; DSA; microstructure; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. LÄS MER
