1. 1. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Rabia Arshad; [2022]
   Keywords : Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

   Abstract : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. READ MORE

3. 2. Lubricants for Hot Stamping of Aluminum: Evaluation of Tribological Behavior and Cleanability

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Barbara Maria Rodriguez Leal; [2021]
   Keywords : Tribology; High-temperature; Metal-forming; Aluminum;

   Abstract : Working at elevated temperature has its challenges due to the high level of complexity whenthe tribosystems operate under harsh conditions, commonly resulting in an increase on thefriction and thermal softening that goes into severe adhesion, severe abrasion and materialtransfer. Despite considerable research, there is a lack of research on tribology applied to hightemperature processes. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Abstract : 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. READ MORE

5. 4. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Gabriel Macêdo; [2020]
   Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

   Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

6. 5. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

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

   Author : Jesper Christensson; [2020]
   Keywords : hot stamping; press hardening; material properties;

   Abstract : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. READ MORE
