Problems solved by technology

However, although the nickel alloys currently on the market are diverse and have a lot of selectivity, they are generally not available or have various defects, such as low performance such as wear resistance, corrosion resistance, and high temperature oxidation resistance, or low performance stability and cost. Therefore, improving the strength of nickel alloys so that they have good comprehensive properties is a hot spot in the development of new nickel alloys. At the same time, the development of high-strength, wear-resistant, corrosion-resistant, and high-temperature oxidation-resistant nickel alloys is important for expanding the application of nickel alloys. domain is important

Description

technical field [0001] The invention belongs to the field of nickel alloy materials, in particular to a novel nickel alloy and a preparation method thereof. Background technique [0002] Nickel is a silver-white metal with a density of 8.9 g / cm3. Melting point 1455°C, boiling point 2730°C, hard, magnetic, good plasticity, good corrosion resistance, nickel is similar to silver-white, hard and malleable metal element with ferromagnetism, it can be highly polished and resistant corrosion. The nickel alloy based on nickel and other elements added has good mechanical, physical and chemical properties. The Monel alloy containing about 30% copper produced around 1905 is an earlier nickel alloy. Alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel-based superalloys, nickel-based corrosion-resistant alloys and shape memory alloys. In today's era of rapid development of science an...
