1. Increased build rate by laser powder bed fusion of SSAB steel powder
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. LÄS MER
2. Modelling Gas Flow Behaviour in Gas Atomizer
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

3. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. LÄS MER
4. Effektivisering av materialflöde i mellanlagerför stångstål
M1-uppsats, Högskolan i Gävle/MaskinteknikSammanfattning : Damasteel är ett företag som tillverkar damaskusstål genom en process av pulvermetallurgiståltillverkning som sker med hjälp av en gasatomiseringprocess. Då Damasteels verksamhet växer har företaget köpt en ny lokal nära produktionsanläggningen. Avsikten är att den nya lokalen ska ersätta det nuvarande mellanlagret. LÄS MER
5. Improving gas flow in gas atomization
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is a cost-effective processing method to produce fine, spheroidized metal powders. During the process, high velocity jets of gas are sprayed at a molten metal stream to break it into small droplets, which will solidify and form the powder particles. LÄS MER
