  1. 1. Modelling of spinodal decomposition in the binary Fe-Cr system

    University essay from KTH/Materialvetenskap

    Author : Viking Roosmark; [2016]

    Abstract : Spinodal decomposition is a phenomenon which hinders the usage of ferrite containing steels under certain conditions. With a better understanding and knowledge of spinodal decomposition new ferritic and duplex stainless steels could be designed. The project is divided into two parts, an experimental part and a theoretical part. READ MORE

    University essay from Linköpings universitet/Linköpings universitet/Nanostrukturerade materialTekniska högskolan

    Author : Hassan Saleem; [2014]
    Keywords : ;

    Abstract : (TixCryAlz)N coatings were deposited on WC-Co substrate using cathodic arc evaporation technique to investigate phase transformation, thermal stability, and high temperature mechanical properties. Two compositions Ti0.34Cr0.33Al0. READ MORE

  3. 3. Evaluation of phase relations in weld overlays of 316, 309MoL and SKWAM

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Fredrik Stenarson; Fritjof Tibblin; [2013]
    Keywords : ;

    Abstract : AREVA NP Uddcomb AB wants to replace the material used for a specific valve seat used in boiling water reactors, BWR. Their solution is a weld overlay of different stainless steels composed of two buffer layers of the steel 309 MoL followed by two layers of the filler material SKWAM welded on type 316 stainless steel or carbon steel.

  4. 4. Growth and Phase Stability of Titanium Aluminum Nitride Deposited by High Power Impulse Magnetron Sputtering

    University essay from Linköpings universitet/Plasma och beläggningsfysik

    Author : Chung-Chuan Lai; [2011]
    Keywords : HiPIMS; co-sputtering; diffusion; microstructure; spinodal decomposition; Ti1-xAlxN;

    Abstract : In this work, we investigate the relation between the diffusion behavior of Ti1-xAlxN at elevated temperatures and the microstructure. Thinfilm samples are synthesized by reactive co-sputtering with two cathodes. READ MORE

  5. 5. Spinodal Decomposition in the Binary Fe-Cr System

    University essay from KTH/Metallografi

    Author : Saeed Baghsheikhi; [2009]
    Keywords : Fe-Cr binary system; phase diagram; miscibility gap; spinodal decomposition; nucleation and growth; hardness; TEM; contrast modulations;

    Abstract : Spinodal decomposition is a phase separation mechanism within the miscibility gap. Its importance in case of Fe-Cr system, the basis of the whole stainless steel family, stems from a phenomenon known as the “475oC embrittlement” which results in a ruin of mechanical properties of ferritic, martensitic and duplex stainless steels.
