  1. 1. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making

    Författare :Yuichi Kanbe; Du Sichen; Leiv Kolbeinsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag metal reaction; equilibrium; kinetics; largest inclusion; statistics of extreme values; electrolytic extraction; cross section; inclusion morphology; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. LÄS MER

  3. 2. Microstructure Evaluation and Wear-Resistant Properties of Ti-alloyed Hypereutectic High Chromium Cast Iron

    Nyckelord :High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance; statistics of extreme values SEV ; maximum carbides size.;

    Sammanfattning : 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 mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER
