Elastic alloys are a type of metallic alloy material, mostly containing two or more metallic elements, in which elastic strain energy is obtained by means of combination of high elastic modulus, low volume fraction of strain energy accumulation and suitable combination of strain rate-sensitive material. The mechanical properties of elastic alloys are higher than those of traditional elastic materials.GB/T15006-1994 is the national standard for elastic alloys in China.
1. Structure and Characteristics of Elastic Alloys
Elastic alloys have a novel composition structure, which is different from traditional alloy structures. Compared with traditional alloys, the structure of elastic alloys has a more complex internal structure, which can greatly increase the strength of the material. In addition, elastic alloys usually have higher elastic modulus and more efficient recovery rate. They also have excellent fatigue and shock resistance and have better thermal stability.
2. Application of Elastic Alloys
Elastic alloys are widely used in various industries due to their excellent performance. Application range includes aerospace, military industry, automotive industry, marine industry and other engineering fields. In particular, elastic alloys are widely used in critical components to ensure their reliability and safety.
In the aerospace industry, elastic alloys are used to manufacture transmission shafts and turbine blades, which are important components for the safe operation of aircraft. In the military industry, elastic alloys are used to manufacture various weapons, and in the automotive industry, elastic alloys are used to manufacture various parts and accessories, such as automobile valves and headlights. In marine engineering, elastic alloys are used to manufacture mechanical parts, such as propellers and ships’ anchors.
3. Manufacturing Process of Elastic Alloys
The manufacturing process of elastic alloys is complex, which involves a series of intricate processes. Firstly, the raw materials used in the production process are carefully selected and then degreased and impurity treated. The next step is to melt the materials in the smelting furnace, followed by the formation of bulky materials. After that, they are put into the rolling mill for hot rolling and cold rolling, which can refine the structure to a certain size, and then anneal to improve the malleability and plasticity. Finally, grinding and other surface treatment processes are conducted to prepare for the final utilization.
4. Testing Method of Elastic Alloys
For the quality inspection of elastic alloys, a series of comprehensive tests are carried out to ensure the quality of the material, including hardness testing, elastic modulus testing, fatigue testing, impact testing, tensile strength and elongation testing, and other tests. In order to obtain accurate test results, the test method must be in strict accordance with the national norms and standards.
5. Standard of Elastic Alloys
The standard of elastic alloys is set according to the performance of the materials. GB/T15006-1994 is the national standard for elastic alloys in China. According to this standard, the properties of elastic alloys include tensile strength, yield strength, elongation rate, hardness, stress-strain curves and fatigue fracture resistance. Therefore, the quality of elastic alloys needs to meet certain criteria in order to reach the standard.
Elastic alloys are widely used in various industries due to their excellent properties, but their quality should also meet the standard. GB/T15006-1994 is the national standard for elastic alloys in China, which provides the criteria for the quality evaluation of elastic alloys. The manufacturing process of elastic alloys is complex and various tests are conducted for its quality control. Only by strictly controlling the quality of elastic alloys can its excellent performance be truly demonstrated.
