1. 1. Inoculant measurement with thermal analysis

   Master-uppsats, KTH/Materialvetenskap

   Författare :Christopher Armstrong; [2020]
   Nyckelord :Thermal Analysis; Inoculation; Nucleation; Compacted Graphite Iron; CGI; Cast Iron; Material Properties;

   Sammanfattning : Over time the level of inoculant will decrease due to fading and this needs to be compensated bymore additions of inoculant. When casting CGI400 at Scania a one-step method is used, and the inoculant additions are based on the last ladle from the previous oven. LÄS MER

3. 2. Infuence of matrix and alloying on the fatigue crack propagation and fracture toughness of compacted graphite iron for cylinderheads

   Master-uppsats, Linköpings universitet/Konstruktionsmaterial

   Författare :Leny Gonzalez; [2020]
   Nyckelord :compacted iron cylinder head fracture toughness fatigue crack propagation alloying;

   Sammanfattning : The constants modernization in the fuels used request improvements in the combustioneffectiveness, as a consequence the material for components as the cylinder heads mustenhance their properties. Seven different compositions of compacted graphite iron (CGI)are analysed with the aim of characterized and select the most suitable material for thecylinder head service condition. LÄS MER

4. 3. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Erik From; [2020]
   Nyckelord :;

   Sammanfattning : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. LÄS MER

5. 4. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

   Master-uppsats, KTH/Materialvetenskap

   Författare :Yang Yang; [2020]
   Nyckelord :Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

   Sammanfattning : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

7. 5. Effects of Austempering Process on Mechanical Behavior Properties of Compacted Graphite Iron

   Master-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning; Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design

   Författare :INAMUL HASSAN; [2019]
   Nyckelord :AusCGI;

   Sammanfattning : The thesis paper here focuses on the effects of the austempering temperature (TA) and the austempering time (tA) on the unalloyed fully ferrite Compacted Graphite Iron (CGI), to obtain improve in mechanical properties and the study of the microstructure. The unalloyed CGI samples were austenitised at 850oC for 60 and 90 min and were then heat treated at 275, 325 and 375oC with different holding times at 30,60,90, and 120 mins. LÄS MER
