Strengthening of Tantalum

In refractory metals, the ductile-brittle transition temperature of tantalum is lower than -196℃, which has the best low-temperature plasticity. While maintaining this characteristic, it should be alloyed to increase its high-temperature strength. Tantalum alloys can be strengthened by solid solution strengthening, precipitation strengthening and a combination of both. The best solid solution strengthening elements are […]


Nitinol Applications

Although many nitinol applications are not well-known to the public, some applications are quite routine and familiar. The spectacle frame made of Nitinol severely deformed and then returned to normal. Similarly, a few years ago, when mobile phone antennas were made of Nitinol, they could bend without breaking or permanently bending. Another superelastic application of […]

It is […]


Machining processes of tungsten Ⅱ

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The most important properties of tungsten are high melting point and high density. Meanwhile, the hardness is high and its ductility is poor to other refractory metals. All the properties make tungsten metal hard to be machined, here we will introduce […]


Rare earth intermetallic compounds

Rare-earth intermetallic compounds are metal compound phases formed between rare-earth metals and other metals or similar metals. They mainly use the special physical and chemical properties of rare-earth intermetallic compounds to prepare new rare earths for various purposes using various processing and manufacturing techniques. Functional Materials. At present, there are the following rare earth metal […]


Introduction to Pyrolytic Boron Nitride (PBN)

Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high temperature pyrolysis reaction by chemical vapor deposition method. Speaking of boron nitride, we must first talk about […]


Magnetic characteristics of permanent magnetic materials

Magnetism is the basic property of matter as well as force, heat, electricity and light. Materials with ferromagnetism are usually called magnetic materials. The biggest characteristic of magnetic materials is the hysteresis behavior, that is, the magnetization M changes with the external magnetic field. When H returns from a certain state to zero, M still […]
