Apparent Viscosity and Structure in Partially Solidified Hyper-Eutectic Al-Mn Alloy under Stirring

Precipitation in a Ni - Al - Mo Directionally Solidified Eutectic Composite

The most recently developed high temperature materials are known as in-situ composites or directionally solidified eutectics. Since the composites are formed during solidification, they have excellent morphological stabilities up to near their melting temperatures. The Ni-Al-Mo system has received the greatest attention for recent several years(1)~(3) since the alloy is expected to form a struc...

Structure of molten Al and eutectic Al–Si alloy studied by neutron diffraction

Growth directions in directionally solidified Al–Zn and Zn–Al alloys near eutectic composition

Growth directions and crystallographic orientations of solidification microstructures have been measured in Al–Zn alloy near the eutectic composition. Al dendrites in Al–92 wt.% Zn alloy were found to grow along the h110i directions while Zn dendrites in Al– 96 and 98 wt.% Zn have h10 10i trunks. In the lamellar eutectic, a crystallographic relationship has been found between the dense plane of...

Effect of Mn and Fe on the Formation of Fe- and Mn-Rich Intermetallics in Al–5Mg–Mn Alloys Solidified Under Near-Rapid Cooling

Mn was an important alloying element used in Al-Mg-Mn alloys. However, it had to be limited to a low level (<1.0 wt %) to avoid the formation of coarse intermetallics. In order to take full advantage of the benefits of Mn, research was carried out to investigate the possibility of increasing the content of Mn by studying the effect of cooling rate on the formation of Fe- and Mn-rich intermetall...

Effect of Thermomagnetic Treatment on Structure and Properties of Cu–Al–Mn Alloy

The paper studies the influence of magnetic field on magnetic and mechanical properties of Cu-Mn-Al alloy under annealing. The comparative analysis of the magnetic field orientation impact on solid solution decomposition processes in a fixed annealing procedure is held using the methods of low-field magnetic susceptibility, specific magnetization, and microhardness test. The paper highlights ch...
