3. 2. Rheocasting of aluminium alloys : Process and components characteristics

   Författare :Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheocasting; aluminium alloy; RheoMetal TM process; microstructural characteristics; component properties and performance; robust design process;

   Sammanfattning : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. LÄS MER

4. 3. Simulation of Microstructure-based Mechanical Behaviour of Cast Components

   Författare :Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Franco Bonollo; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; structural analysis; mechanical behaviour; casting process simulation; Finite Element Method FEM simulation;

   Sammanfattning : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. LÄS MER

5. 4. Optimized Development Process for Cast Components

   Författare :Andreas Holmström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Development process; time discretization; thermo-metallurgical simulation; multi-disiplinary optimization;

   Sammanfattning : In developing trucks, cast components of low weight andhigh durability need to be developed and produced. Cast componentsrepresent an estimated 10-15 percent of the total weight of atruck. There is a strong coupling between the production processand the mechanical properties of a cast component such as it'sstrength. LÄS MER

7. 5. Metal Expansion Penetration During Solidification of Grey Cast Iron

   Författare :Izudin Dugic; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thennal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; meta! expansion penetration; eutectic cell size.; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The meta! expansion penetration has been examined experimentally. The whole casting process was simulated using a commercial software, in order to investigate the solidification characteristics and the pore formation in the casting studied. LÄS MER
