AbstractAbstractMicrosized γ-TiAl powders with composition of Ti–50Al (at.-%) and Ti–48Al–2Cr–2Nb were consolidated using a rapid consolidation technique called plasma pressure compaction (P2C®) to obtain samples near gamma, duplex fully lamellar microstructure. The exhibited minimal grain growth during consolidation, thereby retaining superior mechanical properties. properties varied significantly microstructure type, size alloy composition. Samples average 5 μm the best set flexure...
The tensile properties, fracture toughness, and fatigue crack growth (FCG) characteristics of a directed energy deposited precipitation hardened stainless steel (grade: PH15-5; age hardening heat treatment condition: H900) were examined. In the as-fabricated condition, alloy contains microfissures that are oriented parallel to build direction, whose appearance was difficult be detected using optical microscopy. Due their relative orientation w.r.t. loading significant anisotropy in FCG...
Plasma pressure compaction (P2C) is a novel sintering technique that enables the consolidation of silicon carbide with nanoscale microstructure at relatively low temperature. To achieve high final density optimized mechanical properties, effects various factors pertaining to temperature-time profile and were characterized. This paper reports design experiment approach used optimize processing for 100 nm SiC powder focused on four factors: temperature, time, pressure, heating rate. Response...
We report galvanic deposition of Mo films onto 6061 Al alloy from aqueous solutions containing 1 mM HNO3 and 10 MoCl5. Deposition for 40 min. yields an 9 μm thick film, which also contains 18 atom% Al. The corrosion resistance the film is studied by voltammetry electrochemical impedance spectroscopy in 0.5 M H2SO4 3.5 wt% NaCl electrolyte at pH 2, 7 12. These demonstrate that significantly improves underlying substrate. Galvanic appears to yield elemental, amorphous films.
