Introduction
Tungsten-Iron, commonly known as W-Fe, is an alloy of tungsten and iron that is used in various applications due to its unique properties. It is characterized by exceptionally high corrosion and oxidation resistance, extreme toughness, and a very high melting point. The alloy has been used for many years in the production of machine parts and tools, and is now being used as a material for armor and other applications in the defense sector.
History of W-Fe
The first use of W-Fe dates back to the 13th century when it was used to make weapons, such as swords and spears. The alloy was later used in jewelry and as a decorative material. In the 19th century, W-Fe was discovered to have unique properties that made it suitable for use in industry. The alloy was subsequently used to manufacture machine parts and tools.
In the 1960s, the Soviet Union adopted the use of W-Fe for the production of armor. The alloy, with its high corrosion and oxidation resistance, can be used for many applications that require strong structural components. This includes the production of protective armor, shields, and helmets for soldiers. In the 1970s, the Soviet Union adopted the GOST 17293-71 standard for the production of W-Fe. This standard describes the specifications for tungsten-iron alloys, such as their chemical composition, mechanical properties, heat treatment processes, and other important characteristics.
Composition of W-Fe
The GOST 17293-71 standard specifies the chemical composition of tungsten-iron alloys. It requires that the alloy contain between 60-64 weight percent tungsten and 36-40 weight percent iron. Additionally, the standard requires that the alloy contain no more than six weight percent of other elements, such as carbon, silicon, manganese, and phosphorus.
Properties of W-Fe
The properties of W-Fe can vary depending on the composition of the alloy and the heat treatment process used. Generally speaking, the alloy has an exceptionally high melting point, excellent thermal conductivity, and an exceptionally high hardness. It is also highly resistant to wear, corrosion, and oxidation.
The alloy is characterized by extreme toughness and can be used for applications that require components that can resist impact and shock. Additionally, the alloy has a high degree of elasticity and can be used to manufacture components and tools that require flexibility.
Applications of W-Fe
W-Fe alloys are used for a wide range of applications due to their unique properties. The alloy is commonly used for the production of tools, machine parts, and components for mechanical engineering and industrial automation. Additionally, the alloy has been used to manufacture protective armor and shields for soldiers in the defense industry.
Conclusion
W-Fe is an alloy of tungsten and iron that has special properties that make it suitable for a variety of applications. The alloy is characterized by an exceptionally high melting point and excellent thermal conductivity, and also has excellent corrosion and oxidation resistance. The Soviet Union has adopted the GOST 17293-71 standard for the production of tungsten-iron alloys, which outlines the chemical composition and other important characteristics. W-Fe alloys are used for a wide range of applications due to their unique properties, including the production of machine parts, tools, and armor for the defense industry.
