1. Modulations in Intermetallic Families of Compounds
Sammanfattning : This thesis is based on a study of five distinct intermetallic systems with the aim of expanding the general knowledge of aperiodically modulated crystal structures. Families of compounds that contain a variety of superstructures together with incommensurately modulated structures have been investigated mainly by means of single crystal X-ray diffraction and higher dimensional structure models.

2. Role of alloying elements in Mo5Si3 intermetallics
Sammanfattning : The role of alloying elements in the intermetallic compound Mo5Si3 was studied in the alloying systems Mo5-xMxSi3 (M = Cr, Ti, Nb, Ni, or Co, x = 0.5-2). The effects of the alloying elements were examined by characterising the microstructures and identifying the resulting phases. In the case of Cr and Nb alloying, a solubility of 25% (at. LÄS MER
3. Mechanical Properties of Gamma Titanium Aluminides
Sammanfattning : In recent years intermetallic compounds have attracted a great deal of attention as structural materials. Among the intermetallics, gamma titanium aluminides (.gamma.-TiAl) are considered to be closest to application. LÄS MER
4. Study of Ni3Al- and MoSi2-based Materials for High Temperature Structural Applications
Sammanfattning : In general, the potential of current conventional high-temperature materials has been exploited to a large extent. The industries are therefore looking forward to development of alternative materials for their industrials application, which would be lighter, stronger and having improved higher temperature potential compared to the presently available alloys.

5. Magnetic frustration and low-dimensional magnetism : in transition metal fluorophosphates and square-lattice intermetallic compounds
Sammanfattning : Solids can display a variety of vastly different magnetic properties. Besides the generally well known ferromagnets, antiferromagnets with their antiparallel arrangements of magnetic moments can exhibit a wide range of complex magnetic behavior such as magnetic frustration or low-dimensional antiferromagnetism.
