Grain refinement, Microstructural characterization, and tensile properties of die-cast AZ91 alloy via Lead and Tin additions

Effects of different amounts of lead (Pb) and tin (Sn) on microstructure and tensile properties of the AZ91 alloy were studied. The results presented that the microstructure of AZ91 alloy is consisted the α-Mg phase and semi-continuous network of β-Mg17Al12 intermetallics. For the as-cast AZ91 alloy, the average grain siz and the β phase volume fraction were 96.2 µm and of 25.3%, respectively. ...

Characterization of the Dendritic Microstructure of Investment Cast Alloy 718

The as-cast alloy 718 shows a multiphasic structure which consists of dendrites, carbides and Laves phases. The amount, size, shape, and dispersion of these phases affect the properties and the processing which follows, This structure was characterized by measurements of volume fraction, size, dispersion, and shape factor of carbide and Laves phases. Secondary arm spacing and Vickers hardness w...

EFFECTS OF HOT ISOSTATIC PRESSING ON THE TENSILE PROPERTIES OF A356 CAST ALLOY

The influences of age hardening and HIP (Hot Isostatic Pressing) on the mechanical properties of A356 (Al 7Si 0.6 Mg) casting alloys were studied. Cast bars were homogenized, heated and maintained at a temperature of 540°C for a duration of 2 hours, followed by rapid cooling in a polymeric solution. The castings were age hardened at 180°C for a duration of 4 hours before being subjected to HIP ...

Evaluation of Simultaneous Effect of Melt Filtration and Cooling Rate on Tensile Properties of A356 Cast Alloy

The combined influence of both melt filtration and cooling rate on the microstructure features and mechanical properties of A356 cast alloy was studied. A step casting model with five different thicknesses was used to obtain different cooling rates. The effect of melt filtration was studied by using of 10 and 20 ppi ceramic foam filters in the runner. Results showed that secondary dendrite arm ...

Effect of Microstructural Variations on the Tensile and Fracture Toughness Properties of Alloy 718 Welds

The effect of microstructural variations on the tensile and fracture toughness properties of Alloy 718 welds is reviewed. The microstructural parameters surveyed include heat treatment, longterm thermal aging and neutron irradiation. The two heat treatments that were characterized include the conventional heat treatment, per ASTM B637, and a modified heat treatment designed to improve the tough...
