Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The Condition of Machined Surface of Titanium Alloy in Dry Grinding
Procedia Engineering, 2017 Abstract The Versa 3D twin-beam electron microscope was used to study the relief and chemical composition of the VT3-1 titanium alloy surface after grinding with the ceramic bonded silicon-carbide wheel without grinding fluid. The results show that the process of infeed grinding of titanium alloy is associated with adhesive and cohesive processes ...
