1. 16. Solidification Modeling of Microsegregation

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Souzan Hammadi; [2018]
   Nyckelord :Solidification; casting; microsegregation; Thermo-Calc; DICTRA;

   Sammanfattning : A phase transformation from liquid to solid phase takes place when the material solidifies. Limited diffusion during this phase transition causes microsegregation, which is aphenomenon during solidification that leads to the formation of secondary phases andconcentration gradients. LÄS MER

3. 17. Numerical Analysis ofLatent Thermal Energy Storage in a Cavity

   Kandidat-uppsats, KTH/Energiteknik

   Författare :Robert Olrog; [2017]
   Nyckelord :;

   Sammanfattning : Latent Thermal Energy Storage (LTES) has drawn attention because the technology is a simple and cost-efficient method to store large amounts of energy. Latent energy is either stored or released when the material inside the LTES undergoes phase-change. LÄS MER

4. 18. Improvement of Dredged Sediments : A laboratory study on dredged sediments with different types of binders

   Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Abdul Siddik Hossain; [2017]
   Nyckelord :;

   Sammanfattning : tabilization and solidification (S/S) technique have been the most frequently used method for dredgedsediment improvement in Sweden and worldwide. As dredging activities are essential for safe navigationof ships and vessels that may processes harmful substances or organic pollutants to causecontamination of the surrounding environment. LÄS MER

5. 19. Numerical modelling of centrifugal casting process

   Master-uppsats, KTH/Materialvetenskap

   Författare :Jun Yin; [2016]
   Nyckelord :mathematical modeling; centrifugal casting; funnel; flow behavior; flow patterns;

   Sammanfattning : The centrifugal casting process is a common method for manufacturing the tubes, etc. Due to its high temperature and invisible mold, it is really difficult to know the mechanism of molten steel inside the mold. LÄS MER

7. 20. Characterization of Laser Deposited Alloy 718

   Master-uppsats, KTH/Materialvetenskap

   Författare :Pengcheng Cao; [2016]
   Nyckelord :Additive; Deposition; Alloy 718;

   Sammanfattning : Additive Manufacturing (AM) is a method of producing three-dimensional objects using additive processes. It allows great flexibility in the processes and reduces the design-to-production time. Laser Metal Deposition (LMD) is one of AM methods under development and is based on the deposition technology.
