In this study, rheological and thermal decomposition behavior of AISI 4605 MIM feedstock investigated using capillaryand thermogravimetric analysis. For this purpose and in order to find the critical solids loading, the feedstock was preparedby compounding AISI 4605 micro powder (~ 4 μm) with an adopted multi-component wax-based binder system at variouspowder loadings (53–61 vol%). After preparing the feedstock with optimal solids loading, fundamental rheological characteristicsof homogenized feedstock, including flow behavior index (n), flow activation energy (E), and general moldabilityindex (αstv) were studied. Furthermore, thermal analysis of feedstock, including apparent debinding activation energy andmaster decomposition curve was investigated. The results showed that critical solids loading of feedstock is around 58 vol%. The flow behavior index of developed feedstock was acceptable, since it came out to be less than one. Also, flow activationenergy which shows the sensitivity of material to temperature changes, came out to be 70.406 kJ/mol. Using these two parameters,general moldability index was calculated to be 2.3147E−06. Finally, the master decomposition curve of feedstock wasconstructed based on calculated apparent debinding activation energy and verified using decomposition curves at differentheating rates of 2, 5 and 10 °C/min.
