A comparison of experimental observations and computer simulations shows that trends in the occurrence and severity of center cracks in direct-chill (DC) cast ingots due to different initial casting speed histories may best be explained by the changes in v ...
The ZONMET model of metal condensation is a FORTRAN computer code that calculates condensation with partial isolation-type equilibrium partitioning of the 19 most abundant elements among 203 gaseous and 488 condensed phases and growth in the nebula of a zo ...
The invention concerns injectable bone filling cements, in particular hydraulic calcium phosphate cements, the latter being prepared from at least two initial liquid or pasty constituents comprising each a species reactive in solution or in suspension, the ...
Hot tear formation has been observed during the solidification of a succinonitrile–acetone (SCN-acetone) alloy by pulling the columnar dendrites in the transverse direction with a stick. It is observed that the cracking of the mushy zone (hot tears) always ...
The mechanical properties of continuous fibre reinforced metals (CFRMs) are known to be very sensitive to the selection and composition of the metallic matrix; for aluminium based CFRMs, commercial alloys are not suitable for this purpose. In the present s ...
This article describes a method of constructing parametric models out of captured motion and skeleton data. Casting the problem as scattered data interpolation, our work is based on a multi-step approximation for the interpolation function with motion data ...
This paper describes the synthesis of two novel tetra 2-bromoisobutyric acid-substituted perylene fluorophores and their use as initiators for the atom transfer radical polymerization of styrene. Different star-shaped polystyrenes covering a wide range of ...
As for most of the topics in the field of solidification, Mert Flemings has always pioneered new ideas. While much of the understanding of hot tearing formation was already known about 30 years ago, he devised with Metz an interesting apparatus for studyin ...
Thermodynamic analysis of the compositional profiles across large chemically-zoned Fe,Ni metal grains in the Bencubbin-like chondrite Queen Alexandra Range (QUE) 94411 suggests that these grains formed by non-equilibrium gas-solid condensation under variab ...
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was used to measure distributions of the siderophile elements P, V. Cr, Fe, Co, Ni, Mo, Ru, Rh, Pd, W, Re, Os, Ir, and Pt in metal grains in the metal-rich chondrite QUE94411 with a sp ...
