1. Improved high velocity cold copaction processing : polymer powder to high performance parts
Abstract : A uniaxial High-Velocity Compaction (HVC) process for polymer powder using a cylindrical, hardened steel die and a new technique with relaxation assist was tested with a focus on the compactibility characteristics and surface morphology of the compacted materials using various heights of relaxation assist device with different compacting profiles. Relaxation assist device was presented as a new technique to reduce springback, pull-out phenomenon and to improve the compaction process. READ MORE

4. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density
Abstract : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. READ MORE

5. High pressure vulcanization : crosslinking of diene rubbers without vulcanization agents
Abstract : High pressure vulcanization (HPV) is defined in this thesisas crosslinking of rubber materialsat elevated pressure andtemperature, without the use of any vulcanization agents. Thisis atotally new vulcanization technique, not used in theindustry today. READ MORE
