Abstract
Abstract Mechanical alloying is a powder processing technique in which repeated cold welding and fracturing of powder particles was done in high energy ball mill to produce a homogenous material. In this work, Brass matrix composites with different weight percentages of aluminium nitride (AlN) was synthesized through MA. The necessary amount of powders was milled to capitulate different compositions such as Brass-0 wt.% AlN, Brass-4 wt.% AlN, Brass-8 wt.% AlN and Brass- 12 wt.% AlN composites. The SEM and EDAX tests were conducted on the milled composite powders to investigate about their characterization. The SEM analysis established the homogeneous sharing of AlN in the Brass matrix. The green compacts were prepared and were sintered using electric muffle furnace under controlled atmosphere for a time period of 3 hr. The SEM images of the sintered composite samples ensured the uniform distribution of AlN in the matrix exclusive of pores. The outcome exposed that the adding together of AlN with the Brass matrix improved the mechanical properties of the brass matrix composites
