Amorphous alloy is a kind of metallic materials prepared by rapidly cooling the alloy melt through hindering crystallization in cooling process. Due to the unique structure of atomic random packing, Fe-based amorphous alloys exhibit not only structur

Bulk metallic glasses are prepared in Pd40.5Ni40.5SixP19−x (x = 0–14 at.%) alloys by a combination of flux treatment and water quenching technique. It is found that the thermal stability of the Pd40.5Ni40.5SixP19−x glassy alloys depends on the

We report that binary bulk metallic glasses can be made up to 6 mm in diameter in a Pd–Si alloy system by air cooling at slow cooling rate (about 8 K/s). The high stability of the undercooled liquid and the large glass-forming ability (GFA) of the

We prepare Pd40.5Ni40.5P19 glassy samples with purified ingots by copper mold casting at a high cooling rate and by water quenching at a low cooling rate. Both of them exhibit different supercooled liquid regions and multiple glass transition charact

A numerical simulation of the flow field during solidification in Al-alloy was corried out by the ANSYS 55 in the present paper. The simulation results were in good agreement with the experimental data. It was found, through the simulation, that n
