Ultra High Strength Steel

Intercritically treated ultra high strength steel was investigated using a continuous annealing simulator of the laboratory. The results have shown that the microstructure consists of a ferrite matrix with martensite. A satisfactory mechanical property was obtained by intercritical annealing and subsequent overaging. The specimen exhibited optimum Rm (1360MPa) and At (20%), a relatively low Rp0.2/Rm (0.72) and an ideal product of Rm and At (27200MPa%). Satisfactory mechanical properties of the present steel are attributed to the fact that the effect of dispersion strengthening of martensite islands as well as the contribution to strength by the softer phase, such as ferrite (retained austenite).

Currently, the use of composite materials is increasingly used in various areas of the national economy, including the aviation industry. The materials of this article are devoted to the study of the use of composite materials for the manufacture of aircraft landing gear in comparison with the traditionally used brand of steel. As a result of the work carried out, it was found that the slope made of carbon fiber showed a critical stress twice as high as its design made of 30xgsn2a steel. In addition, carbon plastics are superior to high-strength steel in terms of specific strength, stiffness, and tensile strength.
