Growth of Secondary Dendrite Arms of Fe C Alloy during Transient Directional Solidification by Phase-field Method

Due to the variations in the local solidification conditions in typical industrial casting processes, dendrites grow under transient rather than steady-state conditions. In this study, the phase-field method was used to study the evolution of secondary den ...

The early German production and use of modern hydraulic binders: between English influences and the search for a scientific approach, 1817-1839

Salvatore Aprea

The interest of German building masters towards hydraulic binders grows at the third decade of the 19th century. This acute interest is stimulated by the import of «Roman Cement» from England and by the acquisition of the knowledge related to it. The disse ...

Stress-Strain Predictions of Semisolid Al-Mg-Mn Alloys During Direct Chill Casting: Effects of Microstructure and Process Variables

Jean-Marie Drezet, André Phillion

The occurrence of hot tearing during the industrial direct chill (DC) casting process results in significant quality issues and a reduction in productivity. In order to investigate their occurrence, a new semisolid constitutive law (Phillion et al.) for AA ...

Prediction of Hot Tear Formation in Vertical DC Casting of Aluminum Billets Using a Granular Approach

Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia

A coupled hydromechanical granular model aimed at predicting hot tear formation and stress-strain behavior in metallic alloys during solidification is applied to the semicontinuous direct chill casting of aluminum alloy round billets. This granular model c ...

Dynamic response of a rock fracture filled with viscoelastic materials

Jian Zhao, Wei Wu, Jianbo Zhu

Rock fractures filled with viscoelastic materials, such as sand, usually contribute to rock mass instability under the influence of seismic waves and dynamic loads. The purpose of this study is to verify that the specific fracture stiffness and the specifi ...

Gas injection tests on a Sand Bentonite Mixture: Investigation on the effects of pore water chemistry

Lyesse Laloui, Alessio Ferrari, Donatella Manca, Mohammad Monfared

In this study a series of swelling and breakthrough tests were performed on a target S/B mixture in proportion 80/20 in dry mass. Tests were carried out on specimen compacted to the same dry density but changing the osmotic suction of the pore water. The t ...

RESIDUAL STRESSES IN AS-CAST BILLETS: NEUTRON DIFFRACTION MEASUREMENT AND THERMOMECHANICAL MODELING

Jean-Marie Drezet

Stress relief treatment is often required prior to sawing aluminum DC cast products in order to prevent crack formation and significant safety concerns due to the presence of high residual stresses generated during casting. Numerical models have been devel ...

Photoinactivation of virus on iron-oxide coated sand: enhancing inactivation in sunlit waters

Tamar Kohn, Brian Pecson, Loïc Decrey

Adsorption onto iron oxides can enhance the removal of waterborne viruses in constructed wetlands and soils. If reversible adsorption is not coupled with inactivation, however, infective viruses may be released when changes in solution conditions cause des ...

HOT TEARING SUSCEPTIBILITY IN DC CAST ALUMINUM ALLOYS

Jean-Marie Drezet, André Phillion

Hot tearing and loss of dimensional stability are two key defects related to industrial aluminum alloy casting processes. In order to investigate their occurrence, a new semi-solid constitutive law [20] for AA5182 that takes into account cooling rate, grai ...
