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.

Precision Fe-Ni Alloy Processing Physical Properties Sealing Alloy

These include other Fe-Ni grades, Fe-Ni-Co and Fe-Ni-Cr alloys. A full range of alloys has been produced in relation to major glasses supplied by major manufacturers including Schott, Corning, NEG and Ashai. These glasses for electronics are selected for specific physical, chemical or optical properties, and the selection of the associated sealing metal depends on the glass and sealing type (matching or compression).

precision fe-ni alloy processing other application areas

Other fields of application, such as telecommunications, aerospace engineering, cryogenic engineering (LNG tankers), etc., require high dimensional stability with temperature, or in combination with other materials such as glass, ceramics or composites.

Advantages of precision fe-ni alloy processing

Thermal characteristics of Fe-Ni Invar is closer to glass and ceramics and thus were useful for glass-metal and ceramic to metal joints. This alloy is used in containers used for transport liquid natural gas on tankers as the alloy has minimum cryogenic shrinkage.

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%
