1. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. LÄS MER
2. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell ProduktionSammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER
3. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. LÄS MER
4. BETONG OCH BRANDSPJÄLKNING : Aktuella lösningar för brandspjälkning
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : Dense, damp concrete structures can be damaged by fire. Concrete spalling in the event of a fire causes serious damage to concrete structures, which entails significant economic conse-quences as well as the risk of putting human life at risk. LÄS MER
5. Variations in material properties of grey cast iron and its impact on tool wear
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell ProduktionSammanfattning : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. LÄS MER
