A Granular Model of Equiaxed Mushy Zones: Formation of a Coherent Solid and Localization of Feeding

The gradual transformation of a mushy zone during alloy solidification, from a continuous liquid film network to a fully coherent solid, has been simulated using a granular model. Based on a Voronoi tessellation of a random set of nucleation centers, solid ...

Shape-Controlled Growth of Micrometer-Sized Gold Crystals by a Slow Reduction Method

Francesco Stellacci

Micrometer-sized gold crystals have been synthesized through a binary mixture of amine ligand molecules in the presence of a gold precursor under slow growth conditions (see picture). A wide range of morphologies in the form of triangles, octahedra, pentag ...

Non-isothermal tensile tests during solidification of Al–Mg–Si–Cu alloys: Mechanical properties in relation to the phenomenon of hot tearing

Jean-Marie Drezet

An original set-up has been used to study the mechanical properties of aluminium alloys in tension during solidification with a high cooling rate (70 K/s). The mechanical behaviour of 6056 aluminium alloy with and without grain refiner has been investigate ...

A study of the diffusion brazing process applied to the single crystal superalloy CMSX-4

Alexander Schnell

Diffusion Brazing (DB) of nickel-based superalloys is a standard joining process widely used in gas turbine industry. The DB technique uses a low melting nickel-based filler material, which contains a rapidly diffusing melting point depressant (MPD) such a ...

Gases, liquids and crystals in granular segregation

Pedro Miguel Nunes Pereira de Almeida Reis

We report the results of an experimental investigation of segregation in a binary mixture of dry particles subjected to horizontal oscillatory excitation. The thin layer of particles was driven by the stick-slip frictional interaction with the surface of a ...

Experimental study of the out-of-equilibrium behavior of the two-way shape memory effect

Yves Bellouard, Reymond Clavel

The Two-Way Shape Memory Effect (TWSME) has been widely studied in the literature. However, little attention has been paid about the out-of-equilibrium behavior of the TWSME. This paper reports some experiments, which were performed on specimens, previousl ...

Granular Segregation as a Critical Phenomenon

Pedro Miguel Nunes Pereira de Almeida Reis

We present the results of an experimental study of patterned segregation in a horizontally shaken shallow layer of a binary mixture of dry particles. An order parameter for the segregated domains is defined and the effect of the variation of the combined f ...

Separation of binary mixtures by thermostatic sweeping gas membrane distillation I. Theory and simulations

Urs von Stockar, Ian William Marison

A math. model describing a novel sweeping gas membrane distn. (SGMD) configuration is presented and the sepn. of two volatile components from binary mixts. by this membrane process is theor. investigated. SGMD configuration is modified by using a thermosta ...

Extrinsic contributions to the piezoelectric response of lead-based ferroelectrics

The present study aims at a better understanding of the high piezoelectric properties encountered in lead-based ferroelectrics by focusing on the extrinsic contributions to the response. The main characteristics of these materials are the highly nonlinear ...

Non-isothermal fusion bonding of polypropylene

Pierre-Etienne Bourban, John Christopher Plummer

The fusion bonding of neat polypropylene (PP) has been investigated under non-isothermal conditions with different initial adherend temperatures, and the results compared with results from bonds prepared under isothermal conditions with identical adherend ...
