3. 12. Assessment of ceramic raw materials in Uganda for electrical porcelain

   Författare :Peter Wilberforce Olupot; Stefan Jonsson; Thommy Ekström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; porcelain; characterisation; bending strength; dielectric strength; Uganda; Chemical engineering; Kemiteknik;

   Sammanfattning : Clay, quartz and feldspar are widely available in Uganda. The location and properties of various clay deposits are reported in the literature, but little is reported on feldspar and quartz deposits. In this work an extended literature on ceramics and porcelains in particular, is documented. LÄS MER

4. 13. Numerical simulation of shape rolling

   Författare :Stanislav Riljak; Stefan Jonsson; Peter Gudmundson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire-rod rolling; finite-element method; generalized plane-strain; dislocation density; material model; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. LÄS MER

7. 15. A study of surface temperature and heat flux estimations in heating processes by solving an Inverse Heat Conduction Problem

   Författare :Patrik Wikström; Wlodzmierz Blasiak; Björn Palm; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : The topic of this thesis is estimation of the dynamic changes of the surface temperatureand heat flux during heating processes by using an inverse method. The local transient surface temperature and heat flux of a steel slab are calculated based on measurements in the interior of the slab. LÄS MER
