Effects of microstructure on room temperature fatigue crack initiation and short crack propagation in Udimet 720Li Ni-base superalloy
No full textAn assessment of the effects of microstructure on room temperature fatigue crack initiation and short crack propagation in a Ni-base superalloy is presented. The assessment was carried out on microstructural variants of U720Li, including as-received U720Li, U720Li-LG (large grain variant) and U720Li-LP (large intragranular coherent ?? variant). Fatigue tests were carried out at room temperature using a 20Hz sinusoidal cycling waveform on plain bend bars. Tests were conducted in 3-point bend under load control with an R-ratio of 0.1. A maximum load of 95% ?y was used in all tests. Room temperature fatigue crack initiation was noted to occur due to slip band cracking and from porosity on or just beneath the surface in all materials. Crack propagation was noted to be highly faceted (due to planar slip band cracking) immediately after crack initiation followed by a transition to a flatter Stage II type crack path as crack length increases. U720Li-LP was noted to show the longest fatigue lifetime, followed by U720Li-LG while U720Li shows the shortest life. The longer lifetime of U720Li-LP was linked to a higher resistance to both fatigue crack initiation and short crack propagation. U720Li and U720Li-LG show approximately similar crack initiation resistance although U720Li-LG showed slightly improved short crack growth resistance. The observations have been rationalised in terms of the microstructural characteristics of the materials, and it is believed that larger grain size, larger coherent ?? precipitate size and higher volume fractions of both coherent and primary ?? precipitates will improve overall fatigue lifetimes in PM Ni-base alloys which exhibit planar slip characteristics at room temperature
Influence of localized surface plasmon excitation in silver nanoparticles on the performance of silicon solar cells
No full textSilver nanoparticles have been fabricated on glass and silicon substrates, and silicon solar cells, by evaporation of 10 nm layers followed by thermal annealing. Distinct localized surface plasmon resonances are observed in the optical spectra of the annealed samples, and these strongly affect the cell reflectance and spectral response, both positively and negatively. At short wavelengths photocurrent is improved due to forward-scattering by quadrupolar modes, while at longer wavelengths photocurrent is deteriorated due to back-scattering by dipolar modes. Back-scattering is attributed to modification of the angular scattering distribution of the nanoparticles by the silicon substrate
Notes on the History of the Sale Room of the Egyptian Museum in Cairo
No full textThe author retraces the history of the Sale Room of the Cairo Museum, from the first sales at the Boulaq Museum to the more organised ones at the Giza Museum, up to the Sale Room of the Cairo Museum, still exhisting at the beginning of the 1970s. This latter date is attested by some pages of the Register of the Sale Room, of which some photographs are preserved in the Archives of the Statale University of Milan. The supervisors of the Sale Room through the years are presented, as well as some case studies, including the gifts of State
Merle Collins - b. 1950
No full textThorunn LONSDALE: How did you start your writing career? Merle COLLINS: With my short story “The Walk” [from Rain Darling] in 1977 which I wrote after a workshop in Grenada. And this was the first piece I ever remember performing. T.L.: In that story, do you think the ending is amusing, when Queen realizes that for the money spent on food and drink on the long walk across the island they could have got the bus? M.C.: No, not really. It was more the different perception involved – that aspect ..
