  1. 1. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  3. 2. Approximation of General Semi-Markov Models Using Expolynomials

    University essay from KTH/Matematisk statistik

    Author : Niklas Nyholm; [2021]
    Keywords : applied mathematics; Markov modelling; Semi-Markov process; approximation theory; expolynomial; phase-type distribution; reliability analysis; tillämpad matematik; Markov modellering; Semi-Markov process; approximations teori; expolynom; phase-type fördelning; riskanalys;

    Abstract : Safety analysis is critical when developing new engineering systems. Many systems have to function under randomly occurring events, making stochastic processes useful in a safety modelling context. However, a general stochastic process is very challenging to analyse mathematically. READ MORE

  4. 3. Quantified safety modeling of autonomous systems with hierarchical semi-Markov processes

    University essay from KTH/Optimeringslära och systemteori

    Author : Olle Mattsson; [2020]
    Keywords : probability theory; stochastic processes; reliability engineering; applied mathematics; quantified safety; markov processes; markov chains; sannolikhetsteori; stokastiska processer; säkerhetsteknik; tillämpad matematik; markovprocesser; markovkedjor;

    Abstract : In quantified safety engineering, mathematical probability models are used to predict the risk of failure or hazardous events in systems. Markov processes have commonly been utilized to analyze the safety of systems modeled as discrete-state stochastic processes. READ MORE
