  1. 1. Analysis of granulated carbide powder and how it affects pressing

    University essay from KTH/Materialvetenskap

    Author : Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Keywords : Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Abstract : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. READ MORE

  3. 2. Evaluation of new powder grade for furnace control pieces in sintering process

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Selma Halilovic; [2021]
    Keywords : ;

    Abstract : To be able to supervise the quality of a sintering process, furnace control pieces are therefore used. The current furnace control piece is not sensitive enough small variations during insert production. READ MORE

  4. 3. Influence of slurry viscosity on cemented carbide powder properties

    University essay from KTH/Materialvetenskap

    Author : Isha Anirudha Patankar; [2020]
    Keywords : Cemented carbide powder; Slurry viscosity; Spray drying process; Powder characterization; Hårdmetallpulver; Slamviskositet; Spraytorkning; Pulverkarakterisering;

    Abstract : Cemented carbide powder production is the first step in the manufacturing of cemented carbide inserts.The quality of the powder affects the successive process steps in the production of the cemented carbide inserts. The powder is produced by spray drying of a slurry. The slurry consists of polymer, water, ethanol, and dry components. READ MORE

  5. 4. Design of cemented carbide with Ni-based superalloy binder strengthened with y’-Ni3Al precipitates

    University essay from KTH/Materialvetenskap

    Author : Oscar Edholm; [2018]
    Keywords : Cemented Carbide; Super alloy; Ni-alloy; Ni-Super alloy; Superalloy; Ni3Al; NiAl; Gamma Prime; Gamma; Precipitates; Ni3Al Precipitates; Master Alloy; Liquid Phase Sintering; Cementerad karbid; Hårdmetall; Superlegering; Ni-legering; Ni-Superlegering; Superalloy; Ni3Al; NiAl; Gamma Prim; Gamma; Precipitates; Ni3Al Precipitates; Mästerlegering; Utfällning;

    Abstract : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. READ MORE

  6. 5. Ageing tests of cemented carbide powders : An investigation for increased quality of metal cutting inserts

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Eric Rösth; [2018]
    Keywords : cemented carbide; ageing; PEG; water absorption; sintering; DEK; DMK; coercivity; saturation magnetization; Hårdmetall; åldring;

    Abstract : In this study, the ageing effects on powder used for cemented carbide insert production are examined. Ageing is throughout this study, defined as the time dependent change of the magnetic properties: coercive field strength and saturation magnetization. READ MORE
