Intermetallic Catalysts Intermetallics with long-range chemical ordering have been demonstrated to be excellent catalysts in many reactions. Their surface structures under real reaction conditions are crucial for understanding the catalytic mechanisms. In article number 2100011 by Xiao Li, Jianxiong Zhao and Dong Su, structural changes of intermetallic systematically discussed. Strategies impro...
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. ...
In this research, effect of time and temperature of TLP process on the microstructure, mechanical properties and corrosion resistance of CP-Ti to 316L stainless steel joint evaluated. For this purpose pure copper foil with 100 µm thickness was used as interlayer and joining process carried out at 950˚C, 1000˚C and 1050˚C and for 90, 120 and 150 minutes. After the joining process, shear and micr...
Synthesis, Structure and Bonding of SrCa2In2Ge: A New Zintl Phase with an Unusual Inorganic π-System
The Zintl concept provides an effective and useful way to describe the chemical bonding in a wide variety of main group intermetallic structures. The success of the concept in rationalizing the syntheses and discovery of complex Zintl phases has enhanced its validity as an effective approach in the search for new polar intermetallics and for rationalization of their chemical bonding.1-5 In eval...
