1. Nucleation and growth of martensite in steel
Sammanfattning : .... LÄS MER
2. Low Temperature Austenite Decomposition in Carbon Steels
Sammanfattning : Martensitic steels have become very important engineering materials in modern society. Crucial parts of everyday products are made of martensitic steels, from surgical needles and razor blades to car components and large-scale excavators. LÄS MER
3. Development of Structural Steels for Powder Bed Fusion - Laser Beam
Sammanfattning : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. LÄS MER
4. Martensitic Transformation in High Carbon Steels - Martensite Tetragonality and Impact of Cooling Rate
Sammanfattning : Case-hardened gears are an essential part of our every day life in their role of power transmission in cars and heavy-duty trucks. The increasing use of low pressure carburizing (LPC) for case-hardening in combination with high pressure gas quenching (HPGQ) for cooling opens new possibilities in the design of heat treatments for improved fatigue performance. LÄS MER
5. Influence of Microstructure on the Machinability of Prehardened Mould Steels
Sammanfattning : Mould steels are mainly employed in moulding of plastic products, and also some metals withlow melting temperature such as magnesium alloys. The ever-growing usage of plastics in theindustry, especially the automotive industry, and in everyday life, has increased the utilizationof mould steels. LÄS MER
