Rapid melting and quenching with microsecond current pulses
(Elsevier, 1988-01)
We report the use of microsecond current pulses to transform layered crystalline Ni---Zr films to amorphous alloys. The starting materials were electron-beam- or sputter-deposited multilayers with a composition modulation ...
Ultrastructural and microanalytical results from echinoderm calcite: Implications for biomineralization and diagenesis of skeletal material
(Elsevier, 1984)
Magnesian calcite skeletal elements of the modern crinoid echinoderm Neocrinus blakei were studied using high resolution TEM, high voltage TEM and STEM microanalysis. Unlike inorganic magnesian calcites which are compositionally ...
Determination of phase equilibria in the system Si-Al-Zr/N-O by experiment and thermodynamic calculation
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1981-11)
The phase relations in the system Si-Al-Zr/N-O are studied by experiment and by thermodynamic calculations. The results show the conditions under which such ceramics can exist and thereby explain contradictions between ...
Plane-strain crack-tip fields for power-law hardening orthotropic materials
(Elsevier, 1986-12)
Near-tip stress and strain fields for power-law hardening orthotropic materials under plane-strain conditions are presented. Plastic orthotropy is described by Hill's quadratic yield function. The angular variations of ...
