his study used quantitative image analysis to examine the effect of powder forming method on a population of dense heterogeneities that could e imaged in partially sintered alumina using optical microscopy. Powder pressing resulted in a higher area fraction of dense heterogeneities than lip casting. Extreme value analysis was used to predict the size of the largest heterogeneity in the populati...
Hot pressing process is very popular for thin plates in metal forming. However, the process mechanism for thick plates of high strength steel at high temperature deserves more investigations. The process is characterized by thermo-mechanical behaviors, three-dimensional unsteady deformations and high nonlinearity. In this paper, the model of the process for manufacturing large and thick blades ...
In the steel industry, development of a coke production technology that uses low-grade coal is desired. Decarbonization by use plant biomass also an important option. A candidate formed coke, which produced forming non-coking using binder, followed carbonization. Kraft lignin, by-product in pulp and paper mills potential binder because it aromatic polymer dissolved from wood. this study, therma...
Prediction model for the pressing process in an innovative forming joints technology for woodworking
Explosive powder compaction is one of the developed methods of powder metallurgy that has been investigated due to the limitations of the traditional powder metallurgy. In the process in order to achieve higher density, instead of pressing force the energy released by the explosion of an explosive is used to compact and sinter the powder simultaneously. Explosive powder compaction can be done b...
