2. 1. Phase Distribution of Mixed Biopolymer Gels in Relation to Process Conditions

   Author : Pernilla Walkenström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gelatin; whey protein; phase distribution; shear; high pressure; rheological properties; microstructure; mixed gels;

   Abstract : The influence of various process parameters on the microstructure and rheological properties of pure and mixed gels of gelatin and whey proteins has been investigated. Gelatin is a cold-set protein and whey proteins are a group of thermo-set globular proteins. Depending on the charge present, whey proteins can form two types of gel structures. READ MORE

4. 2. An Atom-Probe Tomography Study of Phase Separation in Fe-Cr Based Steels

   Author : Jing Zhou; John Ågren; Peter Hedström; Hänninen Hannu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Cr alloys; Ferritic stainless steels; Spinodal decomposition; Phase separation; Atom probe tomography; Radial distribution function RDF ; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Stainless steels are very important engineering materials in a variety of applications such as in the food industry and nuclear power plants due to their combination of good mechanical properties and high corrosion resistance. However, ferrite-containing stainless steels are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation of the ferrite phase, where it decomposes into Fe-rich ferrite (α) and Cr-rich ferrite (α').

5. 3. Optimizing liquid phase sintering of ferrous powder metallurgical materials

   Author : Henrik Borgström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface chemical analysis high speed steel; Vacuum annealing; nitrogen alloying; liquid phase sintering;

   Abstract : The properties of powder metallurgical, PM, components are dependent on that the dilemma of full density and suitable microstructure is resolved. Whilst it is often possible to achieve full density, it may or may not coincide with a suitable microstructure. READ MORE

6. 4. Theoretical Investigations of Two-Dimensional Materials : Studies on Electronic, Magnetic, Mechanical, and Thermal Properties

   Author : Xin Chen; Biplab Sanyal; Susanne Mirbt; Kristian Sommer Thygsen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2D materials; DFT; Structure search; Functional materials; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Two-dimensional (2D) materials have been paid enormous attention since the first realization of graphene in 2004, in connection to high-speed flexible electronics, 2D magnetism, optoelectronics, and so on. Apart from graphene, many new 2D materials with special properties have been predicted and synthesized. READ MORE

7. 5. Deformation and martensitic phase transformation in stainless steels

   Author : Peter Hedström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Abstract : The use of high-energy synchrotron x-rays which has enabled three- dimensional structural characterization from the nano- to the macroscopic scale, and now to the meso-scale, such as individual grains and dislocation structures, is a major scientific advance. This is the first technique with sufficient spatial resolution and penetration power to probe the local structure embedded deep within the material. READ MORE
