Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.
Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.
Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.
Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.
Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.
Affected by the ever-changing international situation, the supply and prices of international bulk Vanadium Nitride VN, Vanadium Nitride VN Overview, Vanadium Nitride VN Application, Vanadium Nitride VN Supplier, Vanadium Nitride VN Price are still very uncertain.
Overview of vanadium nitride VN powder
Vanadium nitride is formed during the nitriding process of steel and increases wear resistance. During the nitridation process, another phase V2N (also known as vanadium nitride) can be formed together with VN. VN has a cubic rock salt structure. There is also a low-temperature form, which contains the V4 cluster. The low temperature phase is caused by dynamic instability when the vibrational mode energy in the high temperature NaCl structural phase drops below zero.
Vanadium nitride is a strongly coupled superconductor. Nanocrystalline vanadium nitride is said to have potential for use in supercapacitors. The properties of vanadium nitride are sensitively dependent on the stoichiometry of the material.
How is vanadium nitride VN powder produced?
The samples made of ammonium metavanadate powder and carbon powder were pre-reduced in a heating furnace, followed by final reduction. After the final reduction is completed, the sample is cooled with the furnace, and the obtained sample is vanadium nitride; in the process, the temperature in the heating furnace is 650-670° C., and the holding time of the heating furnace is 2-4 hours. Under the conditions of this temperature and holding time, the surface of the sample can be prevented from melting and hindering the reduction reaction.
After pre-reduction, the main reduction product of the sample is V2O3, and the rest are carbides and a small amount of VN; in the final reduction process, the sample is kept at 1300-1500 °C. CO gas and CO gas are generated during the insulation process. The introduced nitrogen gas is taken away, and VN is obtained after the insulation is completed; the nitrogen flow rate during the reaction is 210-270 mL/min, which can not only meet the kinetic conditions of the reduction reaction, but also prevent the reaction temperature caused by too much nitrogen. reduce and waste nitrogen;
Application of vanadium nitride VN powder
Vanadium nitride has high wear resistance, which can greatly improve vanadium steel after nitriding.
The comprehensive mechanical properties of high-strength steel, such as strength, toughness, ductility, and thermal fatigue resistance, endow the steel with good weldability. In the case of achieving the same strength, adding vanadium nitride can save 20-40% of the vanadium addition, thereby reducing the cost.
Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron. Vanadium Nitride Alloys for High Strength Low Alloy Steels
Vanadium nitride can carry out effective vanadium-nitrogen microalloying at the same time, promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and play a more effective role in strengthening sedimentation and refinement.
Adding vanadium nitride to steel can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, so that the steel has good weldability.
In the case of achieving the same strength, adding vanadium nitride can save 30-40% of the vanadium addition, thereby reducing the cost. Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron.
The vanadium-nitrogen alloy used for high-strength low-alloy steel can simultaneously carry out effective vanadium-nitrogen microalloying, promote the precipitation of carbon, vanadium and nitrogen compounds in the steel, and play a more effective role in sedimentation strengthening and graining. refinement.
