Military use From the perspective of military industry, as long as one thousandth of zirconium is added to the steel, the hardness and strength will increase dramatically. Zirconium-containing armor steel, cannon forging steel, stainless steel and heat-resistant steel are important materials for the manufacture of armored vehicles, tanks, cannons and bulletproof panels. From th...

Powdered iron is mixed with zirconium nitrate and can be used as a flash powder. Metal zirconium is used almost exclusively as a cladding for uranium fuel components in nuclear reactors. Also used in the manufacture of photographic flashlights, as well as corrosion-resistant containers and pipes, especially resistant to hydrochloric acid and sulfuric acid. Zirconium chemicals c...

Zirconium has a small thermal neutron capture cross section and outstanding nuclear properties. It is an indispensable material for the development of atomic energy industry and can be used as a reactor core structure material. Zirconium powder is easy to burn in the air and can be used to detonate detonators and smokeless gunpowder. Zirconium can be used as an additive for deo...

A zirconium alloy is a colored alloy formed by adding zirconium as a matrix to other elements. The main alloying elements are tin, antimony, iron, and the like. Zirconium alloy has good corrosion resistance, moderate mechanical properties, low atomic thermal neutron absorption cross section in high temperature and high pressure water and steam at 300-400 °C, good compatibility ...

Zirconium is also widely used in the vacuum industry. It can be used to make beautiful golden yellow. The industry has zirconium and titanium. It is also made of zirconium or titanium. Some people think that zirconium is closer to real gold. Hue, today I will talk about zirconium. Zirconium readily absorbs hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxyge...

(6) Double annealing The difference between double annealing and isothermal annealing is that in the first stage after double annealing, the alloy is cooled to room temperature in air, and then the alloy is reheated to the temperature of the second stage (this temperature is lower than the temperature of the first stage). The advantage of double annealing is that a part of the ...

Isothermal annealing Isothermal annealing: The workpiece is heated to a higher temperature sufficient for recrystallization to be cooled, and then cooled to a temperature at which the β phase has high stability (this temperature is generally lower than the recrystallization temperature), maintained at this temperature, and then cooled in air. Compared with simple annealing, the...

Vacuum annealing The hydrogen content of the titanium alloy surface layer is reduced to a safe concentration, eliminating the possibility of hydrogen embrittlement. In addition, the residual stress is reduced and the mechanical properties and performance of the alloy are ensured. The purpose and significance of the above four heat treatments are clear, but the concepts of isoth...

Recrystallization annealing The annealing process is performed by heating the workpiece to a temperature above the recrystallization temperature. In this annealing, recrystallization mainly occurs, so that work hardening is eliminated, the structure is stabilized, and the plasticity is improved. The annealing temperature is between the recrystallization temperature and the phas...
