In 1804, after smelting metallic nickel from ore, due to the limitation of technical conditions and lack of resources at that time, there was no significant development of nickel in about 100 years. Until the eve of the First World War, the world's nickel output was only a few thousand tons. After the first, especially after the Second World War, the nickel output increased sharply.
In 1865, Garnier reductively smelted silico-magnesium-nickel ore, added gypsum and coal, and obtained a nickel mirror after reduction, thereby enriching a small amount of nickel in the original ore. After burning off the sulfur, the obtained nickel oxide is reduced with carbon in the solid state to make nickel.
Nickel can be completely dissolved in r-iron, and its solubility in a-iron is 10%. The nickel content of 5% can improve the tensile strength and hardness of low-carbon structural steel. Carbon steel contains 3% nickel, which can improve its tensile strength, impact toughness, yield point and deformability. NiCrMo structural steel containing 1% to 4% nickel is very suitable for use in automobile, locomotive and machine manufacturing because of its proper ratio of tensile strength to mass. In addition to these elements, wear-resistant components also contain carbon. The important nickel-containing steel grades and users are stainless steel and heat-resistant special steel. For example, a series of heat-resistant stainless steels such as Cr18Ni9Ti and Cr17Ni1iMn2 have good thermal processing properties and are widely used in machinery, medical treatment, national defense, and light industry.
Nickel has a slight graphitization effect in cast iron. It can stabilize pearlite and reduce ferrite content. Therefore, the nickel in cast iron helps to obtain a uniform and integrated structure and good performance. Adding a small amount of nickel (Ni0.%~1.0%) will result in the formation of fine pearlite. When the nickel content is high, martensite and austenite will be formed. The fine and stable pearlite can make cast iron have good processing performance and hardness. Therefore, nickel-added iron castings can be used to manufacture castings in the automotive industry.
A low-iron-nickel alloy containing chromium, diamond, and aluminum. When high-temperature alloys are used, it is generally called Hastelloy, and its tensile strength is as high as 233. 24MPa at 923°C. Iron-nickel alloys containing 30% to 90% Ni have high magnetic permeability, so they are suitable for electrical and electronic industries, such as Claymax alloys containing 30% Ni and 70% Fe. The alloy containing Ni80%, Cr14%, Fe6% is a special corrosion-resistant spring material used in dental treatment. Nickel is also used as coins and in the battery industry.
