  2. 1. Nanoindentation characterization of high chromium white cast iron for assessment of machining performance

    Author : Ling Chen; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanoindentation; FEM; Characterization; High chromium cast iron; Machining; Grid nanoindentation;

    Abstract : As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. READ MORE

  4. 2. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron

    Author : Qiang Liu; Pär Jönsson; Keiji Nakajima; José Tinoco; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance;

    Abstract : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). READ MORE

  6. 4. Depth Profiling of the Passive Layer on Stainless Steel using Photoelectron Spectroscopy

    Author : Wendy Fredriksson; Kristina Edström; Fredrik Björefors; Sannakaisa Virtanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; depth profile; stainless steel; passive film; XPS; HAXPES; corrosion; powder metallurgical; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The physical properties of the protective passive films formed on the surface of stainless steels under electrochemical polarization in different electrolytes were studied. The structure of these films was analyzed as a function of depth using photoelectron spectroscopy (PES). READ MORE
