Aluminium (Al 99.99 % purity) and aluminium alloy Al-5.7Ni and Al-5Mg (wt.%) open-cell foams made by replication processing are creep-tested in the temperature range T/Tm=0.5-0.8, varying the relative density between 0.10 and 0.25. Steady state creep rates ...
Laboratory tests and inverse methods are used for the determination of the thermophysical properties of a CuCrZr alloy. The solidification path (temperature versus solid fraction curve) is determined using the Single Pan Thermal Analysis (SPTA) technique d ...
This work describes the dilute solution and solid-state structure of polyelectrolyte complexes generated from hyperbranched polylysine (HBPL) and various anionic, sodium alkyl sulfate surfactants. In dilute solution, the radius of gyration (Rg) of the HBPL ...
Al-Zn-Si alloy coatings are widely used for the corrosion protection of steel sheets. In addition to the favorable corrosion properties, the Al-43wt%Zn-1.6wt%Si coatings present several features which are of metallurgical interest. The first one is their s ...
Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
Hot cracking is a spontaneous failure of an alloy during solidification. It is a severe problem for casting industry as it reduces the productivity of cast houses and limits the range of alloys compositions that can be industrially produced. Hot tears occu ...
Hot tearing, one of the most severe defects observed in castings, is due to both tensile stresses and lack of interdendritic liquid feeding in the mushy zone. In order to predict this phenomenon, the two-phase averaged conservation equations for mass and m ...
Nowadays the joining of dissimilar materials is often the only solution to fulfill the complex requirements of high technology applications. One of the fields in which the research activity is more intense and promising is that of the brazing of ceramics w ...
Particle reinforced metal matrix composites are manufactured by high-pressure infiltration. These composites contain roughly 50% by volume of discrete alumina inclusions dispersed homogeneously in a continuous aluminium-based matrix. Three matrices, namely ...
Powder synchrotron X-ray diffraction studies confirm that 7-oxabicyclo[2.2.1]heptane, (oxanorbornane), forms three solid phases on cooling and four on warming, as previously indicated by spectroscopic and DSC meas urements. The two highest temperature phas ...
