Optimizing Rheological Behavior of Steel Feedstocks in Advanced Process of Alloying Powder Injection Molding
The rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. Powder loading is one of the important factors that have a great distribution on rheological behaviors. By using the gas atomized spherical 316L stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...
متن کاملEffects of Micro and Nano Sized SiC Powder on the Rheological Properties of Al Based Feedstocks for Low Pressure Injection Molding
This study investigates the effects of micro- and nano-sized SiC powder on the rheological behavior of Al based feedstocks for powder injection molding (PIM). Different compositions of Al feedstocks with additions of micro and nano-SiC powder were prepared and their rheological properties were measured with a rotational rheometer. The effects of SiC content and shear rate were investigated and...

متن کاملEffect of a Carboxylic Acid on Rheological Properties of a High Alumina Cement Mortar
In this work, we studied the effect of carboxylic acid on the rheological properties of a high-alumina cement mortar (CH45) produced by the Algerian firm REFRACTAL.The investigated properties are setting time, water consumption, electrical conductivity, pH, density and the compressive strength. The results show a setting time of about 200 min for the acid...
متن کاملThe Effect of Binder Components and Powder to Binder Ratio on Rheological Properties of Mg-SiC Feedstocks
Rheological characteristics of powder injection molding PIM feedstocks play an important role in final properties of manufactured MMCs. In this study, six formulations composed of magnesium and SiC powder (99:1 wt.%) and a specific binder were prepared to investigate the influence of binder composition, powder to binder ratio, time and temperature on rheological properties of the feedstock. Th...
