Microstructure and mechanical properties of stable austenitic steel after thermomechanical treatment

This paper reports an investigation of the influence of powerful ultrasonic action during compaction on porosity and pore size distribution in ZnO ceramics. Ceramic samples were obtained with a porosity of ~ 1%. It was established that ultrasonic action, without significantly changing the integral value of the porosity of sintered samples, leads to decrease in the relative content of large pores (macrodefects)
