1. The Effect of Cooling Rate on Sintered Cemented Carbides
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Magnetic measurements are useful tools for quality control of cemented carbides. Previous work at Sandvik Mining and Rock Technology has shown that the coercivity increases with increased cooling rate during sintering for a specific grade. LÄS MER
2. Design of cemented carbide with Ni-based superalloy binder strengthened with y’-Ni3Al precipitates
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. LÄS MER
3. En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik
Kandidat-uppsats, Institutionen för teknikvetenskaperSammanfattning : The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. LÄS MER
