  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. Coupled flux nucleation model applied to the metallic glass AMZ4

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Mattias Tidefelt; [2021]
    Keywords : Material science; numerical modeling; metallic glasses; classical nucleation theory;

    Abstract : Additive manufacturing (AM), also known as 3D-printing, has made it possible to produce components made of bulk metallic glass (BMG) which have remarkable properties compared to parts made of conventional alloys. A metallic glass is a metastable noncrystalline alloy that form if a melt is quenched with a sufficient cooling rate. READ MORE

  4. 3. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Noomi Linder; [2020]
    Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

    Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

  5. 4. Understanding the Effect of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) - As-Built microstructure

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Prakruth Harish; [2020]
    Keywords : Ti 6242; LMD-w; Isothermal transformation diagrams; Microstructure of Ti 624;

    Abstract : The most widely used titanium alloy in the hot sections of a jet engine is Ti-6Al-2Sn-4Zr-2Mo (Ti-6242) and with the technological advancements additive manufacturing (AM) of Ti-6242 is of great interest. Although, there is not much published related to additively manufactured Ti-6242. READ MORE

  6. 5. Key performance indicators for resilience when disturbance occur in the Swedish railway system

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Olle Frid; Jakob Grehn; [2016]
    Keywords : Resiliens; systemresiliens; järnvägssystem; nyckeltalsinventering; motståndskraft; anpassningsförmåga; återställningsförmåga; störning; punktlighet; kapacitet;

    Abstract : Järnvägen drabbas av olika störningar vilket skapar förseningar i trafiken. Trafikverket och det branschgemensamma samarbetet ”Tillsammans för tåg i tid” (TTT) efterfrågar ett nyckeltal för resiliens. Nyckeltalet ska kunna användas för att mäta resiliens då tåg i det svenska järnvägssystemet drabbats av en störning. READ MORE
