Introduction to precision fe-ni alloy processing

Introduction to precision fe-ni alloy processing

Charles Edouard Guillaume discovered Invar in the 1890s. He was awarded the Nobel Prize in Physics in 1920 for his work on the FeNi system and the discovery of Invar alloys. Iron-nickel alloy (Ni-Fe precision alloy) is a low-frequency soft magnetic material with high magnetic permeability and low coercivity in weak magnetic fields. Early iron-nickel alloys were used for telephone communications, and heat treatment processes and vacuum melting methods were used to improve alloy properties.

What is Fe-Ni-Co alloy developed from?

The Fe-Ni-Co alloy was developed from the Fe-Ni or the Invar alloy. The Invar alloy is the forerunner of a family of controlled expansion alloys and the Invar alloy itself is still used today in vast numbers of household appliances, computer terminals, TV screens, cathode ray tube, advanced electronic components, filter mobile phone networks, telecommunication, aerospace engineering, cryogenic engineering, which require either high dimensional stability or expansion characteristics with variation in temperature.

Frequently Asked Question

Do you have any question?

It has been observed that Fe 1x Ni x alloys are soft ferromagnetic materials for all compositions with very high curie temperature. The Fe metal is of bcc structure (α phase) whereas the Ni metal is of fcc structure (γ phase). The alloy series exhibits a structural transition from bcc to fcc at around Ni concentration of 25% .

The Fe–Ni–Ti alloy system has been evaluated, together with Fe–Ni and Fe-Ti binary subsystems, to provide reliable information for applications and in view of a thermodynamic modelling of the system.

The Fe metal is of bcc structure (α phase) whereas the Ni metal is of fcc structure (γ phase). The alloy series exhibits a structural transition from bcc to fcc at around Ni concentration of 25%
