Examining the Microstructure of Industrial Leaded Brass Blanks for Quality Control

Abstract:

The microstructure of industrial leaded brass blanks made of leaded brass was examined for quality control. The exogenous inclusions and pores in the microstructure of the blanks were found. The microstructure was examined by means of traditional metallographic analysis methods. Is showed the transition from exogenous inclusions and pores, which were not removed in the initial processing stage, to the crack, which leads to billet destruction on one of the last processing stages. An algorithm for calculating the additional pressure that occurs when the mechanical action on the metal having a exogenous inclusions is suggested. Therefore, without the quality control leaded brass blanks a metallographic method, it is impossible to guarantee the reliable operation of machines and responsible purpose constructions.
