Creep of Ni-Al and Ni-Cr-Al Superalloy Foams
The steady-state creep rate of Ni-base metallic foams, with superalloy composition (in wt. pct) Ni7.8∼9.1Al (relative density, ρ = 2.5-2.6) and Ni-13.5∼16.6Cr-5.1∼8.9Al (ρ = 2.8∼3.0), was measured under a range of temperatures (680∼825°C) and applied stresses (0.1∼0.3 MPa), and compared with that of NiAl intermetallic foams (ρ = 5.3). The stress exponent and activation energy are within the exp...
متن کاملConcentrations of microelements Al , Co , Cr , Li , Mo , Ni , Sb and Sr in
Microelements concentrations of Al, Co, Cr, Li, Mo, Ni, Sb and Sr were determined in the milk of Croatian Coldblood mares by inductively coupled plasma-optical emission spectrometry. The total mean element contents in mares milk were (mg/kg): Al<10, Co<10, Cr 26.7, Li 4.35, Mo 11.0, Ni<10, Sb 70.1 and Sr 467. Variation of Li, Sb and Sr concentrations were found throughout the lactation stages (...
متن کاملSynthesis, structure, and mechanical properties of Ni–Al and Ni–Cr–Al superalloy foams
Reticulated nickel foams were alloyed with 8–9 wt% Al or 14–18 wt% Cr and 5–9 wt% Al in a three-step method consisting of (i) gas-phase deposition of Cr and/or Al onto the struts of a pure Ni foam by pack-cementation at 1000 C; (ii) homogenization at 1200 C to remove concentration gradients and to solutionize the alloyed struts; (iii) aging at 900 C to form c0 precipitates within the struts. Th...
متن کاملHot Ductility Loss in a Fe-Ni-Based Superalloy
High temperature tensile tests have been conducted on samples of a Fe-Ni based superalloy, Incoloy A-286, and significant ductility loss has been observed at 1220 °C. Titanium-rich, thin-film-like phase has been found on the inter-granular facets of fracture surfaces. It appears that sulfur content of Ti-rich phase was higher than that of the matrix. At 1220 °C, liquation of Ti-rich phases has ...
متن کاملDetermining the Hot Deformation Temperature Range of Medium Carbon Ni-Cr-Mo Low Alloy Steels using Hot Tensile and Hot Torsion Tests
The aim of this study was to investigate the suitable temperature range for hot deformation of three medium carbon Ni-Cr-Mo low alloy steels by hot tensile and hot torsion tests. Hot tensile tests were carried out in the te,prature range of 850-1150°C at a constant strain rate of 0.1 s-1 until fracture. Then, the tensile flow behavior, hot ductility and microstructural evolution of the steels w...
