6. 5. Binder Migration in Double Pressed Drill Bit Inserts

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Axel Bjerke; [2018]
   Keywords : Physics and Astronomy;

   Abstract : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. READ MORE
