Glass is one of the most significant synthetic materials in human history.During the early Iron Age,the Mediterranean became famous for natron soda-lime glass(m-Na-Ca)with low levels of magnesium and potassium.In cont...
Amorphous metallic alloy (also known as metallic glass) was firstly discovered in the 1960s as a‘‘young"member of the amorphous material family [1]. Their unique metastable disordered structure imparts metallic glas...

The embedded-atom method is adopted to simulate the specific heat capacity of liquid silver. The relationship between the specific heat capacity and the temperature above and below melting point is derived. The result...
A glassy Zr41Ti14Ni8Cu12.5Be22.5Fe2 rod with a diameter of 9 mm was successfully pro-duced by water puenching. The effects of iron addition on thermal stability and hardness of Zr41Ti14Ni8Cu12.5Be22.5Fe2 bulk amorphou...
A series of SiO2 glasses were synthesized by using spectroscopically pure silica on the YJ-3000 multi-anvil apparatus at 355—445℃ and 2.0—5.5GPa. Their spectroscopic characteristics resemble that of the ...
A new method to calculate the formation enthalpies and free energies of compounds based on standard electromotive force of cation,φ0, and free energies of formation, ΔG2980, or forma...
A series of melting experiments was carried out at 1 650℃ and 1.00-3.00 GPa using alkaline basalt as starting material. The compositions of quenched basaltic glasses in the products were detected by electron micro pr...
WITH the temperature decreasing, Cr100-xFex(18≤x≤25) alloys exhibit first a transition from a paramagnetic (PM) state to a ferromagnetic (FM) state and then a second transition from the F...
