   Sammanfattning : Heat treatment is a way to significantly change materials properties. When presented with materials that lack certain mechanical properties, it is possible to change its chemical properties and microstructures by applying heat. This can help achieve better yield strength, ductility and toughness. LÄS MER

3. 2. 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
