1. 1. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

   Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Mayur Mane; [2021]
   Nyckelord :Co-free maraging steels; Co-free W360 AMPO alloy; hot-work tool steel; Selective laser melting; microstructure; wear;

   Sammanfattning : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. LÄS MER

3. 2. Tribological characterisation of additively manufactured hot forming steels

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

   Författare :Anna Vikhareva; [2020]
   Nyckelord :High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

   Sammanfattning : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. LÄS MER

4. 3. High Temperature Tribology in Hot Stamping

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

   Författare :Evan Kurnia; [2019]
   Nyckelord :high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

   Sammanfattning : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. LÄS MER

5. 4. Thermal fatigue and soldering experiments of additively manufactured hot work tool steels

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Henrik Andersson; [2018]
   Nyckelord :Additive manufacturing; 3D printing; Hot work tool steel; Thermal fatigue; heat checking; Die casting; Soldering; AISI H13; Additiv tillverkning; 3D printing; Varmarbetsstål; Termisk utmattning; Värmesprickor; Pressgjutning; Soldering; AISI H13;

   Sammanfattning : Modern manufacturing processes are under a never ending evolvement. Lowered manufacturing costs, higher part quality, shorter lead times and lower environmental impact are some important drivers for this development. Aluminum die casting is an effective and attractive process when producing components for e.g. LÄS MER

7. 5. Investigation of Microstructure and Mechanical Properties in Hot-work Tool Steels

   Master-uppsats, KTH/Materialvetenskap

   Författare :Tomas Rey; [2017]
   Nyckelord :hot-work tool steel; secondary carbide precipitation; precipitation hardening; tempering; carbide reactions; precipitation simulation; microstructure;

   Sammanfattning : Hot-work tool steels make up an important group of steels that are able to perform with good strength and toughness properties at elevated temperatures and stresses. They are able to gain this behavior through their alloy composition and heat treatment, which relies on the precipitation of alloy carbides to counter the loss in strength as the tempered material becomes more ductile.
