  1. 1. High Resolution Microanalysis of Creep Resistant 9-12% Chromium Steels

    Author : Lars Lundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; martensitic stainless steel; TEM; modified 12% chromium steel; creep resistant; atom-probe field-ion microscopy;

    Abstract : This thesis deals with detailed studies of the microstructure of 9-12% chromium steels. Three alloys with improved creep resistance have been studied in different stages of heat treatment and after creep testing. Two of them were manufactured using PM/HIP and were of the type 10.

  2. 2. Alternatives to pickling : preparation of carbon and low alloyed steel wire rod

    Author : Peter Gillström; Magnus Jarl; Sven-Erik Lundberg; Tarras Wanheim; Örebro universitet; []
    Keywords : Mechanical descaling; shot blasting; pickling; steel wire rod; wear; drawing; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

    Abstract : A well established method for scale removal on hot rolled wire rod is pickling. To avoid pollution problems, the wire rod can be mechanically descaled. By this method, the removed scale can be recirculated to the blast furnace. In batch pickling considerable energy is necessary; e. READ MORE

  3. 3. Environmental and health aspects of corrosion– importance of chemical speciation

    Author : Yolanda Hedberg; Inger Odnevall Wallinder; Anna Karin Borg Karlsson; Susanna Wold; KTH; []
    Keywords : ;

    Abstract : During the last decades, the interest in corrosion of metals and alloys from an environmental and health perspective has increased rapidly as a consequence of stricter environmental and human exposure legislations, their extensive use as implant materials and an increasing understanding related to occupational and/or daily exposure to airborne particles. Corrosion-induced metal release, however, needs to be understood in detail and to include knowledge related to chemical speciation, i. READ MORE

  4. 4. Carbon Nitride : Characterization and Protein Interactions

    Author : Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. READ MORE
