   Sammanfattning : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. LÄS MER

3. 2. Investigation of elastic powder properties using analytical powder decompression : Effects of tablet compaction parameters, pressure, speed, and lubrication

   Master-uppsats, Uppsala universitet/Institutionen för farmaci

   Författare :Pardis Babaei; [2020]
   Nyckelord :Pharmaceutical powder; elastic powder properties; analytical powder decompression;

   Sammanfattning : Aim: The objective of this project was to use analytical powder decompression (APDC) in tablet compaction processes to study the elastic behavior of powders. Background: During powder compaction, the particles undergo four stages of rearrangement, plastic deformation or particle fracture, and elastic deformation. LÄS MER
