1. Black liquor gasification : experimental stability studies of smelt components and refractory lining
Sammanfattning : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). LÄS MER
2. Microstructure and phase transformation of Ti-6Al-4V
Sammanfattning : The research described in the thesis concerns phase transformations and fatigue properties in the Ti-6Al-4V alloy. The need to weld the alloy for certain engine components can expose the alloy locally to non-optimum thermal cycles and it is therefore of importance to gain an understanding of the kinetics involved in the phase transformations during heating and cooling.

3. The microstructures of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo and their relationship to processing and properties
Sammanfattning : The research described in the thesis concerns phase transformations and mechanical properties of the titanium alloys Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo. The need to weld the alloys for certain engine components can expose the alloy locally to non-optimum thermal cycles and it is therefore of importance to gain an understanding of the kinetics involved in the phase transformations during heating and cooling.

4. Formation of silicon nitride based materials by nitridation and sintering
Sammanfattning : Todays demands on silicon nitride based materials for structural applications focus on microstructures rendering high strengths and reliability at reasonable costs. This work was mainly aimed at production of sialons for these types of applications by nitridation with subsequent sintering. LÄS MER
