  1. 1. Method to assess machinability of engineering steels using coated carbide tools

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Petra Hedberg; [2021]
    Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested.

  4. 3. Independent Project in Chemical Engineering and Materials Engineering : A literature study of powder-based additive manufacturing

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Daniel Feldt; Petra Hedberg; Asker Jarlöv; Elsa Persson; Mikael Svensson; Filippa Vennberg; Therese You; [2018]
    Nyckelord :Additive manufacturing; selective laser melting; electron beam melting; binder jetting; stainless steel; tool steel; nickel alloys;

    Sammanfattning : The focus of this literary study was additive manufacturing (AM) and the purpose was to find general trends for selected materials that have been additively manufactured and compare them to results from other reviews. The raw materials studied were stainless steels 316L, 17-4 PH, 15-5 PH and 420, as well as tool steel H13 and nickel alloys 625, 718 and Hastelloy X. LÄS MER
