1. 1. Process development and optimization towards binder jetting of Vanadis 4 Extra

   Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Jivesh Jain; [2022]
   Nyckelord :Binder jetting; tool steel; Vanadis 4 Extra; sintering; debinding; wear resistance;

   Sammanfattning : Additive manufacturing (AM) has experienced significant growth and development in recent years, owing to the ability to produce complex parts using a wide range of materials with relative ease. Powder bed-based metal AM has been at the forefront of this growth, even reaching the point where parts can be manufactured for end-use applications. LÄS MER

3. 2. Additive manufacturing of lunar regolith simulant using direct ink writing

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

   Författare :Billy Grundström; [2020]
   Nyckelord :3D printing; additive manufacturing; lunar regolith simulant; european space agency; ESA; in situ resource utilisation; ISRU; direct ink writing; sintering;

   Sammanfattning : In this work, the use of a lunar regolith simulant as feedstock for the direct ink writing additive manufacturing process is explored, the purpose of which is to enable future lunar in-situ resource utilisation. The feasibility of this approach is demonstrated in a laboratory setting by manufacturing objects with different geometries using methyl cellulose or sodium alginate as binding agents and water as liquid phase together with the lunar regolith simulant EAC-1A to create a viscous, printable ‘ink’ that is used in combination with a custom three-axis gantry system to produce green bodies for subsequent sintering.

   Master-uppsats, KTH/Materialvetenskap

   Författare :Oscar Edholm; [2018]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

   Nyckelord :liquid-exfoliated graphene; liquid exfoliated graphene; graphene; sliding contacts; additive in Ag-based sliding contacts; Raman; SEM; EDS; tribometer; liquid exfoliation; liquid phase exfoliation;

   Sammanfattning : This master thesis work is performed at ABB Corporate Research Center inVästerås. The aim of this study is to investigate Ag:graphene composites as slidingelectrical contacts, suitable for use in e.g. tap-changers. LÄS MER

7. 5. Additive Manufacturing of Silicon Nitride

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

   Författare :Céline Montanari; [2017]
   Nyckelord :ceramics; silicon nitride; additive manufacturing; stereolithography; photopolymerization;

   Sammanfattning : This study aims to investigate the fabrication of silicon nitride ceramics via additive manufacturing method. Silicon nitride exhibits excellent thermo-mechanical properties and it is one of the main structural ceramics. The excellent properties of silicon nitride are obtained through densification via liquid phase sintering. LÄS MER
