Effect of Chromium Addition on ZA40 Alloy Fabricated by Powder Metallurgy Method

Abstract

The aim of this study is to develop and investigate the properties of chromium powder-reinforced metal-metal composites using powder metallurgy methods with a ZA40 alloy matrix. To analyze the effect of varying chromium particle amounts on ZA40-Cr composites, samples with chromium weight percentages of 5%, 10%, and 15% were produced. To ensure uniform distribution of chromium particles, the matrix and composite powders were mixed in ball mills for five hours. These powders were then hot-pressed under an argon gas atmosphere at 500°C and 500 MPa pressure for two hours to form the samples. The samples were evaluated by determining the microstructure, hardness, density, and tensile properties of the ZA40-Cr metal-metal composites with varying chromium content. Porosity and relative density results revealed that increasing Cr content increased porosity while reducing relative density. Hardness measurements showed that the sample with 10% Cr addition exhibited the highest hardness value (182 Brinell). However, increased porosity in the 15% Cr sample caused a decline in hardness. Tensile strength tests indicated that the sample with 10% Cr addition achieved the highest strength (240 MPa). The results demonstrated that the reinforcement of the ZA40 matrix with Cr particles at specific ratios enhanced the mechanical performance, but that excessive Cr content adversely affected the properties due to increased porosity. The optimum Cr content was determined to be 10%, providing the best mechanical properties. This study highlights the potential of ZA40-Cr composites as cost-effective and high-performance materials for engineering applications.
