1. 1. Precipitation during Tempering of Martensite in Fe-Cr-C alloys

   Master-uppsats, KTH/Materialvetenskap

   Författare :Chanachon Techaboonanek; [2012]
   Nyckelord :precipitation; microstructure; tempered martensite; Fe-C-Cr alloys; carbide; simulation;

   Sammanfattning : The martensite structure is the most important microstructure in tool steel due to its high hardness. However, a lack of ductility is the major drawback. In order to improve the ductility and still maintaining a suitable hardness a tempering process is needed. LÄS MER

3. 2. An Atom Probe Investigation of Addition of Nitrogen in Hot Work Tool Steel

   Master-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Arbab Rehan; [2012]
   Nyckelord :atom probe tomography; hot work tool steel; carbides; proxigram; iso-surface; Technology and Engineering;

   Sammanfattning : Two different hot work tool steels, QRO 90 and QRO 80N were investigated using atom probe tomography. QRO 90 is a commercial alloy while the other QRO 80N is an experimental test alloy. The main composition of QRO 90 is 0.38C-2. LÄS MER
