Alloys containing molybdenum and tungsten, which include molybdenum-based molybdenum-tungsten alloys and tungsten-based tungsten-molybdenum alloy series.
The phenomenon that the volume and size of the liquid alloy continue to decrease during the cooling and solidification process is called contraction (shrinkage).
Fluidity refers to the ability of liquid alloy to fill the mold.
Titanium is the IVB element in the periodic table. It looks like steel and has a melting point of 1 672 ℃. It is a refractory metal.
The melting point of most alloys is lower than the melting point of any one of its constituent metals
Solid solution alloys, which form solid solutions when liquid alloys are solidified, such as gold and silver alloys
The added alloying elements can form solid solutions, compounds, and produce endothermic or exothermic reactions, thereby changing the metal. The nature of the matrix.
Alloy is a substance with metallic characteristics synthesized by a certain method from two or more metals and metals or non-metals.
