dc.description.abstract | The powder processing methods including powder metallurgy (P/M) and powder injection molding (PIM) techniques for tungsten (W)-rhenium (Re) were employed to produce a W-Re rocket nozzle. The composition of W-Re was determined by 25 wt.% of Re to avoid the formatting brittle sigma (sigma) phase. The samples for analysis of the densification behavior on sintering were prepared by die pressing and cold isostatic pressing (CIP). The feedstock for the PIM process was produced by mixing the W-25 wt.% Re powder and binder system based on a wax-polymer with an optimum solid loading through the twin-extruder mixer. The injection molded specimens were debound to extract and decompose the binders via the solvent and thermal debindings. The debound samples were sintered in a hydrogen atmosphere. After sintering, hot isostatic pressing (HIP) was carried out in an argon atmosphere to enhance the density. The dilatometry experiments were performed to analyze and predict a densification behavior during sintering. The master sintering curve (MSC) model was used to characterize the densification behavior with a minimal set of preliminary experiments. The mechanical properties were evaluated through microstructure and chemical composition measured by EDX-SEM and X-ray diffraction (XRD). Finally, the eroding test was conducted using the W-25 wt.% Re rocket nozzle produced by PIM under the high temperature. After carrying out erosion tests, the erosion rate, hardness and microstructure were evaluated. (C) 2013 Elsevier Ltd. All rights reserved. | - |
