1. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C
Sammanfattning : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. LÄS MER
2. Carbide and MAX-Phase Engineering by Thin Film Synthesis
Sammanfattning : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. LÄS MER
3. Modelling of mechanical properties of MAX-phase materials
Sammanfattning : .... LÄS MER
4. Synthesis and Characterization of New MAX Phase Alloys
Sammanfattning : This Thesis explores synthesis and characterization of new MAX phase alloys (M = early transition metal, A = A-group element, and X = C or N), based on incorporation of M and X elements previously not considered. My primary focus is on M = Mn for attaining magnetic properties, and on X = O for potential tuning of the transport properties. LÄS MER
5. Synthesis and characterization of Ga-containing MAX phase thin films
Sammanfattning : The study of magnetic Mn+1AXn (MAX) phases (n = 1 − 3, M – a transition metal, A – an A group element, X – C or N) is a recently established research area, fuelled by theoretical predictions and first confirmed experimentally through alloying of Mn into the well-known Cr2AlC and Cr2GeC. Theoretical phase stability investigations suggested a new magnetic MAX phase, Mn2GaC, containing Ga which is liquid close to room temperature. LÄS MER
