Titanium nickel alloy, also known as Nitinol, is a binary alloy composed of nickel and titanium. The atomic percentages of these two elements are approximately equal. Austenitic phase and martensite phase Due to changes in temperature and mechanical pressure, Nitinol has two different crystal structure phases, namely an austenite phase and a martensite phase. In […]

Advanced ceramics can be divided into structural ceramics, tool ceramics, and functional ceramics according to their different uses. Structural Ceramics The main materials of structural ceramics are alumina (Al2O3), silicon nitride (Si3N4), silicon carbide (SiC), and hexagon boron nitride ceramics (BN). Alumina (Al2O3) The main composition is Al2O3, and the general content is more than […]

Pyrolytic boron nitride is an anisotropic high-temperature ceramic with high electrical resistance and good thermal conductivity. It is suitable for applications requiring high strength, low thermal expansion coefficient and good thermal shock resistance. Pyrolytic boron nitride also has thermal shock resistance and is a superior sealant that protects graphite from corrosive environments, such as most […]

Nitinol (Nitinol) alloys have many material and device characteristics, for example, kinking resistance, stress constancy, dynamic interference, deflection stiffness, magnetic resonance imaging (MR1) compatibility, radiopacity and biocompatibility. The most famous characteristics of Nitinol are its superelasticity and thermal shape memory. Although the term “shape memory” describes the phenomenon of restoring a predetermined shape by hearing and […]

Niobium is used in the manufacture of products for diverse applications:-High temperature vacuum furnaces, where it is an excellent getter-Nickel based superalloys; and alloyed with titanium or tin-Superconductors-Sodium vapor lamps, where it is resistant to attack by the molten alkali-Synthetic diamonds-Sputtering targets for fiber optic applications or architectural glass-Nuclear reactors it has low thermal neutron cross […]

Rare earth fluorides, metals and slag have strong chemical activity, so the crucible material used must be resistant to corrosion by halogens and their compounds at high temperatures and does not interact with rare earth metals. It can be used for a long time in inert atmosphere. Below we list the chemical stability of different crucible materials […]

High-density tungsten alloy, also known as tungsten-based heavy alloy, is a type of alloy made of tungsten as the matrix element (85% ~ 99% mass fraction) with the addition of Ni, Cu, Fe and other alloy elements by liquid phase sintering. The density is up to 16.5 ~ 19.0g / cc. The most commonly used are […]

Rare earth metals have typical metal properties. They have strong chemical activity and can form a variety of compounds, including hydrides, chlorides, silicides, carbides, organic / inorganic salts and complexes. This is the basis for the rare earth metal in the metallurgical industry as a purification, impurity removal and refinement modifier. Rare earth metals are unstable […]

The finished products of niobium and niobium alloy materials and their processing and preparation processes need to be annealed and heat treated. The heat treatment methods include homogenization heat treatment, stress relief heat treatment, recrystallization heat treatment and mechanical heat treatment. -Homogenization heat treatment. The homogenization heat treatment is to eliminate defects such as metastable phases and […]

Molybdenum-rare earth oxide alloy (Mo-REO), also called rare earth molybdenum, is an alloy of molybdenum and rare earth element oxides, which is an oxide dispersion-strengthened alloy, similar to rare earth tungsten. Commonly used rare earth element oxides are Y2O3, La2O3, CeO2, and Nd2O3, Sm2O3, Gd2O3, and Sc2O3. They are usually added in the alloy in an […]
