Project

Modelling of Diffusive and Massive Phase Transformations in Solids (ME 937)

phase transformation, where the diffusive processes are localized in the interface at the interface. This may cause that a massive phase transformation appearsalso in the two phase region i.e. un...

Modelling of diffusional phase transformations in multicomponent systems with multiple stoichiometric phases (GAP204/10/1784)

of technology. In the case of contact of two different phases at elevated temperatures, new phases may nucleate and grow at the contact and cause its embrittlement or multicomponent systems, the developed models could be used for t...

Revealing the effect of diffusion on formation of the omega phase in metastable beta-Ti alloys micromechanical insight from phase-field modelling (GF24-14578L)

accompanied by several phase transformations. One of the most studied is the β → ω transformation during which nanoparticles of the ω phase are formed. This process is a result of two major mechanisms: elasticity ...

Carbon diffusion in extremely carbon-supersaturated ferrite and austenite alloys (GAP108/11/0148)

We propose to study the rate of carbon diffusion in carbon-supersaturated BCC and FCC phases of chosen Fe and Ni based alloys. The carbon supersaturation may be produced, e.g., as a result of a phase transformation...
