    Modeling of near-net forging of thin-walled parts of strain rate sensitive alloy
    (2005) Bednarek, Sylwia; Sińczak, Jan; Skubisz, Piotr
    Numerical modelling of a single-operation forging process of a radial bladed impeller forging as one piece is presented. The analysis have been performed using high-melting-alloy model material. A several alternative technologies differing in temperature and forming speed. Evaluation of the correctness of a forging process were based on distribution of effective strain, effective strain rate, mean stress as well as fllling of the cavities of a die-impression in thin-walled ribs type areas.

    The forging process of aircraft engines turbine blades
    (2010) Sińczak, Jan; Łukaszek-Sołek, Aneta; Bednarek, Sylwia; Chyła, Paweł
    The aim of this paper was to obtain information about optimum conditions of the forging process of a blade made from high-temperature creep resisting alloy called Inconel 718. A three-dimensional rigid-plastic finite element method (FEM) of forging process of high-pressure compressor rotor's blade analysis has been performed. Various forging process variants were analysed, including isothermal conditions.
