    Notes: An improved hydrodynamic model has been developed for analysis and interpretation of shock-induced chemical reactions in inorganic powder mixtures. Attention is focused on the interaction of hydrodynamic flow with the thermodynamic changes associated with chemical reactions such as specific volume, specific internal energy, and material properties. Predictive capabilities of the model have been illustrated using experimental shock wave profile data involving Ni-Al and Al-Fe2O3 mixtures.

    Notes: A recent investigation of powdered Ni-Al systems subject to shock loading has yielded evidence that reactions occur during the shock front. Time-resolved measurements of normal shock pressure indicate that an "excess pressure'' is generated possibly due to an exothermic reaction in the Ni-Al system. These reactions appear to occur during the 100 ns that represent the shock front. A clear reaction threshold is observed and corroborated by micrographs of the recovered samples.

    Notes: Abstract Diamond powders with silicon additives were shock compressed by using a flyer impact technique. Pressure and temperature histories in the powder mixtures were numerically simulated in order to determine the optimum experimental condition which resulted in the highest Vicker's hardness. This was found to be: an initial diamond particle size of 2–4μm at 7.2 % silicon by volume. The results of the simulations were consistent with the distribution of the microstructure and the microhardness in the compact.

    Notes: Abstract The response of highly porous powder compacts and powder mixtures to high pressure shock compression loading is of considerable interest for synthesis and processing of metals, ceramics and superhard materials. This technical note reports the first successful use of the Bauer piezoelectric polymer stress-rate gauge for measurements of shock wave velocity and stress-wave profiles in porous powder compacts. A powder mixture of 5Ti+3Si shows strong chemical reaction at a pressure of 2.5 GPa, while a powder mixture of 3Ni+Al shows no evidence for reaction at 4.7 GPa. A measurement of compaction of a powder compact of rutile at 5.5 GPa shows that it is not compacted to the solid density state. Although pressure increases due to chemical reaction products in condensed phases are modest and difficult to detect, shock wave velocities provide a sensitive measure of the existence of chemical reaction. The increase in shock speed can be described in terms of constant pressure processes which are descriptive of “ballotechnic” reactions, i.e. shock-induced reactions in heterogeneous material mixtures.

    Notes: Abstract Existing hugoniot calculations of inorganic chemical reactions in powder mixtures are found to contain errors and ambiguities. Most of the problems were caused by improper identification of the thermodynamic reference state. The derivations have been revised using two different integration paths: i) constant volume, and ii) constant pressure. Sample calculations with a Ni-Al system show that the two schemes yield close results. The constant pressure scheme presents the possibility of self-sustained chemical reactions (detonations) occurring in condensed phase. An example of such a detonation in the Ni-Al system is numerically demonstrated with hydrocode calculations.

    Notes: Abstract Use of polymer materials for precision parts in advanced technology requires precise control of production processes such as melting, casting, and cooling processes. To achieve this, a reliable knowledge of thermophysical properties is essential. In the present study, submillisecond measurement of the thermal diffusivity of a flowing polymer melt was performed. Laminar flow of polymer melt through a narrow gap between two parallel plates creates a shear stress in the flow layer which then results in molecular orientation of polymer molecules. Once this orientation takes place, anisotropy of the thermal diffusivity is expected to occur. The method used in the present study was that of the so-called forced Rayleigh scattering method, a high-speed optical method. Nagasaka and Nagashima have recently improved the method significantly and applied it to the measurements on various difficult materials including molten salts. Measurement of thermal diffusivity anisotropy of molten polystyrene was successfully performed. Dependence of the thermal diffusivity and its anisotropy on shear force in flowing polymer melt was studied.

    Notes: Abstract In-situ characterization of powder mixtures of aluminium and nickel-graphite subjected to high-pressure shock-wave compression was performed using optical and transmission electron microscopy. Formation of a polycrystalline diamond phase was observed for the first time as an apparent continuation of graphite fibres. A shear-induced transformation process is suspected. Among various resulting Ni-Al alloy phases NiAl and Ni3Al were predominant and had the characteristics of rapidly solidified nickel aluminide.
