“…Here, dynamic recrystallization is thought to be not the key mechanism due to the following two clues. Firstly, according to previous research, the depth of dynamic recrystallization zone (i.e., zone of grain refinement in Figure 1b) is generally only about 10-30 µm [13,14], which is too thin to be observed. Meanwhile, it can be completely remelted during the depositing of next layer.…”

“…Furthermore, the depth of the equiaxed grain regions observed in Figure 5d is significantly larger than this value. Secondly, dynamic recrystallization can results in very fine grain size (about 20-100 nm) [13,14]. However, the averaged equiaxed grain size is about 20 μm.…”

“…Another example of commercially used technologies of ultrasonic treatment is the surface modification by ultrasonic peening [10][11][12][13]. For instance, high-intensity ultrasound affects grain refinement in alloys and even can be used for nanostructuring of surface layers of materials that results in surface hardening [14].…”

“…Однако их существенным недостатком являются низкие прочностные свойства, которые не улучшаются проведением термической обработки. Перспективным направлением деформационного упрочнения аустенит-ных сталей является применение таких современных методов поверхностного пластического деформирова-ния, как обработка SMAT (surface mechanical attrition treatment) -ультразвуковая обработка шариками в ва-кууме [1], дробеструйная обработка [2; 3], ультразвуко-вая ковка в вакууме [4] и ударная обработка бойками [5], пескоструйная обработка [6] и др. Упрочнение аус-тенитных сталей за счет сильного измельчения зерна наблюдается также при фрикционной обработке с пе-ремешиванием [7].…”
