Witryna20 sty 2024 · Usually, the impurity content in steel is small, but their influence on the technological and strength properties, especially fatigue life and fatigue strength, is significant [ 18, 19, 20, 21, 22 ]. The tendency to form and then develop micro-cracks during variable loads are the factors determining the fatigue life of the material [ 23, … Witryna11 kwi 2024 · Impurities and structural defects such as dislocations lead to the deterioration of the characteristics of SCDs. For instance, nitrogen impurities reduce the mobilities of the charge carriers in SCDs drastically, while dislocation and dislocation bundles reduce SCDs’ strength and optical properties, respectively [ 2, 3, 4, 5 ].
