STRUCTURAL SENSITIVITY PROPERTIES OF BRASS-MODIFIED ALLOYING ELEMENTS
Abstract
The study investigated how the amounts of doping elements affected the tensile behavior and electrical conductivity of Cu-30wt%Zn alloys. The stir-casting method was used to produce the brass after it was mixed with different amounts of niobium and tin (0.1–0.5wt% and 1.0–5.0 wt%). We looked at the resistivity, electrical conductivity, and tensile strength. An energy dispersive spectroscope (EDS) and a scanning electron microscope (SEM) were used to examine the microstructures of the cast alloys. The findings demonstrated that the addition of niobium and tin improved the alloy's electrical conductivity and tensile strength by refining and altering its structure. The highest electrical conductivity was demonstrated by 0.1wt% niobium and tin, while the maximum tensile behavior performances were recorded by 3wt% niobium and 5wt% tin.
