Detection of Heterogeneous Atoms in Thermally Expanded Steel Tubes
Due to the roll strengthening mechanism, increasing the strength of the metal allows the metal to form a solid alloy with another metal (or non-metal). Solid solution alloys or alloys based on solid solution (such as carbon steel) generally have higher strength than pure metals. This phenomenon of adding a solute element to increase the strength of a solid solution is called solid solution strengthening. The thermal expansion of the steel tube is therefore based on the chemical composition of Jincheng (the microstructure of the ferrite in the lattice does not change), and the enhanced metallurgical basis is due to the dislocation and heterogeneity of the movement. The result of interaction between atoms.
For non-alloyed and low-alloy steels, solid solution strengthening can be considered as a strengthening mechanism, independent of the rolling system. The most important alloying elements in steel, Mn.Ni, Cu and P, can form a replacement solid solution and promote a linear increase in yield strength and resistance. The degree of rise of the line can be determined by the coefficient Ac. The strength increase value Ac is a concentration change value of the alloying element. In addition to the replacement elements, the C, N and other elements form a gap in Fe. The solubility of the solid solution in iron is very low (the maximum dissolution of N when the temperature is 585X: the solubility of C when the temperature is 721T: 0.018%) ), and it drops greatly with temperature. Therefore, C and N have little effect on the yield strength and tensile strength in the solid solution content.
