Can a Pressure Standard be Based on Capacitance Measurements?

March 1, 1998

Author(s)

Michael R. Moldover

We consider the feasibility of basing a pressure standard on measurements of the dielectric constant [epsilon] and the thermodynamic temperature T of helium near )[degrees]C. The pressure P of the helium would be calculated using the fundamental constants

March 1, 1998

Author(s)

R E. Napolitano, T H. Sanders

Morphological evolution of a dendritic growth front in a binary alloy is simulated using a cellular automation approach to establish the feasibility of modeling such growth with a local rule-based scheme. The motivation for this work is derived from the

March 1, 1998

Author(s)

J E. Taylor, John W. Cahn

We provide the general outline of an analysis of the motion of diffuse interfaces in the order-parameter (phase field) formulation which includes nondifferentiable and nonconvex gradient energy terms. Nondifferentiability leads to equilibrium and motion

Dynamic and Static Grain Growth During the Superplastic Deformation of 3Y-TZP

March 1, 1998

Author(s)

J Seidensticker, M J. Mayo

While phenomenological theories of superplasticity have often suffered from the fact that a single phenomenological law is not universally applicable to all superplastic systems, it is shown that a universal dynamic grain growth law does apply. The law is
