  1. 1. Optimization of annealing parameters for SANDVIK 13C26 and 20C strip steels : By MODDE analysis and modified JMAK method

    University essay from KTH/Materialvetenskap

    Author : Ahamed Ameen; [2019]
    Keywords : Recrystallization; EBSD; Optimization; MODDE; JMAK analysis; strip steels;

    Abstract : The process optimization of continuous annealing furnace, RHF 125, for recrystallization annealing of two steel grades, Sandvik 13C26 and Sandvik 20C has been carried out. To recreate the continuous annealing process carried out in the roller hearth furnace in the industry, samples with different cold reduction rates were chosen from ongoing production lines.

  3. 2. In Situ Heating During XRD Measurements as a Method to Study Recrystallisation of Aluminium Alloy AA3003

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Louise Bäckström; [2018]
    Keywords : In situ XRD; in situ heat treatment; recrystallisation; rolled aluminium; AA3003;

    Abstract : Recrystallisation is an important topic in the metal industry since the process may drastically alter the properties of the materials subjected to it. By controlling the recrystallisation process, the material properties can be adjusted as desired, which could lead to stronger materials and hence lighter constructions, decreasing our material consumption.

  4. 3. Investigation of Ductility Dip at 1000˚C in Alloy 617

    University essay from KTH/Materialvetenskap

    Author : Julia Sjöström; Helena Åkesson; [2017]
    Keywords : Ductility dip cracking; Ni-based alloy; tortuous grain boundaries; intergranular precipitates; grain boundary migration; superalloy; M23C6; Ti N; C ; solid state cracking; dynamic recrystallization;

    Abstract : Alloy 617 displays a ductility dip during straining at exactly 1000˚C, leading to brittle fracture. A sudden decrease in ductility appearing during Gleeble hot ductility tests of Ni-based superalloys is a well-known phenomenon, while its cause is unknown. READ MORE

  5. 4. Microstructural evaluation of welded sheet metal formed parts

    University essay from Högskolan i Jönköping/JTH, Maskinteknik

    Author : Fredrik Liljestrand; Tornberg Ole; [2015]
    Keywords : Alloy 718; laser weld; bending; recrystallization; cold work; δ-phase; and solution treatment; Inconel 718; Lasersvets; Bockning; Kalldeformation; Rekristallisation; δ-fas; Upplösningsbehandling;

    Abstract : The purpose of this report is to evaluate the hardness and microstructure in bent and welded samples of Alloy 718. The results will be used by GKN aerospace to evaluate the simulated values of the production process of vines in a jet engine. In total, eleven samples from three different production chains are evaluated. READ MORE
