  4. 2. High-Temperature Behaviour of Austenitic Alloys : Influence of Temperature and Strain Rate on Mechanical Properties and Microstructural Development

    Author : Mattias Calmunger; Sten Johansson; Guocai Chai; Johan Moverare; Göran Engberg; Linköpings universitet; []
    Keywords : ;

    Abstract : The global increase in energy consumption and the global warming from greenhouse gas emission creates the need for more environmental friendly energy production processes. Biomass power plants with higher efficiency could generate more energy but also reduce the emission of greenhouse gases, e.g. CO2. READ MORE

  5. 3. On High-Temperature Behaviours of Heat Resistant Austenitic Alloys

    Author : Mattias Calmunger; Sten Johansson; Guocai Chai; Johan Moverare; Hans-Jürgen Christ; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Advanced heat resistant materials are important to achieve the transition to long term sustainable power generation. The global increase in energy consumption and the global warming from greenhouse gas emissions create the need for more sustainable power generation processes. READ MORE

  6. 4. Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2 composites

    Author : Mirva Eriksson; Zhijian Shen; Guocai Chai; Stockholms universitet; []
    Keywords : materialvetenskap; Materials Science;

    Abstract : Titanium has been used as a model substance to study how it behaves in a SPS apparatus when heating rate and/or pressure were varied during the sintering and deformation process. The sintering and deformation of Ti in SPS were compared with that occurring in the conventional hot pressing (HP) in order to reveal if there are any positive effects added by the use of SPS.

  7. 5. Generalised stacking fault energy and plastic deformation of austenitic stainless steels

    Author : Dávid Sándor Molnár; Levente Vitos; Guocai Chai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stacking fault energy; stainless steel; plasticity; deformation; ab initio; Teknisk materialvetenskap; Materials Science and Engineering; Steel Forming and Surface Engineering;

    Abstract : Austenitic stainless steels are primarily known for their exceptional corrosion resistance. They have the face centred cubic (FCC) structure which is stabilised by adding nickel to the Fe-Cr alloy. The Fe-Cr-Ni system can be further extended by adding other elements such as Mn, Mo, N, C, etc. in order to improve the properties. READ MORE
