  1. 1. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Abderrahim Ait ouakrim; [2023]
    Nyckelord :Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

    Sammanfattning : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

  3. 2. Precipitation analysis in bearing steel Hybrid 60

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rebecca Rosén; [2023]
    Nyckelord :martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

    Sammanfattning : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. LÄS MER

  4. 3. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
    Nyckelord :;

    Sammanfattning : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible  as  of  today  to  be able  to  remove  all  of them.  The  inclusions  are  categorised  into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of  nonmetals:  slag, mold).

  5. 4. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates

    Master-uppsats, KTH/Materialvetenskap

    Författare :Monika Rolinska; [2020]
    Nyckelord :Extraction replica; transmission electron microscopy; materials characterization; precipitation; Extraktionsrepliker; transmissionselektronmikroskopi; materialkaraktarisering; utskiljningar;

    Sammanfattning : Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.

  7. 5. Correlating the microstructure with wear properties of aluminium silicon carbides

    Master-uppsats, Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design; Högskolan i Jönköping/JTH, Material och tillverkning

    Författare :Chaitanya Krishna Jammula; [2019]
    Nyckelord :Aluminium silicon carbide; silicon carbide; wear test and scratch test;

    Sammanfattning : Aluminium is one of the metals playing a prominent role in automobile industry after cast iron. Because of its light weight property and good mechanical properties. When aluminium reinforced with silicon carbide showing good tribological properties and improved strength. LÄS MER
