Analysis of the Effect of Composition Ratio Variation in Alloy (Fe/Cu) -0.5al on Mechanical Properties and Micro Structures with Powder Metallurgy

Metal alloys are a crucial component in the material industry, particularly for structural purposes. The main focus of this study is on a blend consisting of iron (Fe), copper (Cu), and aluminum (Al), with various different composition ratios of Fe and Cu, namely 60FE-40CU-0.5AL, 70FE-30CU-0.5AL, 80FE-20CU-0.5AL, and 90FE-10CU-0.5AL. The synthesis process is carried out using a powder metallurgical technique with a compact pressure of 250 MPa and sintering at 1000 °C for 1 hour. Each sample is then tested to obtain data on density, vickers hardness, compressive strength, wear resistance, and micro structure.

Effect of Composition Ratio on Density and Hardness

The analysis shows that the highest density is found in specimens with a ratio of 60FE/40CU, which is 5,4989 gr/cm³, while the lowest density is in the 90FE/10CU ratio with a value of 5,1257 gr/cm³. This difference in density can be attributed to the composition of the elements that affect the density of the material. When the Fe ratio increases, density tends to increase as well, considering that Fe has a higher density than Cu. The addition of Fe in the alloy can increase the density of the material, making it more suitable for structural applications.

In terms of hardness, the test results show that 60FE/40CU has the lowest hardness, which is 63.5 VHN, while 90FE/10CU shows the highest value of hardness, which is 86.8 VHN. This shows that the addition of Cu in the alloy can increase material hardness, so as to indicate the nature of resistance to better deformation. The addition of Cu in the alloy can increase the hardness of the material, making it more resistant to wear and tear.

Compressive Strength and Wear Resistance

The highest compressive strength was observed in the composition of 60FE/40CU with a value of 493.4 MPa, while the lowest value was found in 90FE/10CU, which is 428.5 MPa. Increased compressive strength in certain ratios reflects a better interaction between particles in the metallurgical process of powder. On the other hand, for wear resistance, 60FE/40CU specimens have the highest value, which This shows that the alloy with a higher Fe content has a worse wear resistance. The addition of Fe in the alloy can decrease the wear resistance of the material, making it more prone to wear and tear.

Micro Structure and Porosity

Micro structure tests reveal that along with the increase in Fe levels, the porosity in the FE/Cu-0.5Al blend tends to be reduced. Lower porosity can have a positive impact on the strength of the material, reduce the possibility of damage due to cracks or defects that can affect the structural integrity of the alloy. Increased material strength seen in certain ratios correlates with an increase in density and reduction of porosity, providing an overview of the quality of the alloy produced. The reduction of porosity in the alloy can increase the strength of the material, making it more suitable for structural applications.

Conclusion

In this study, the variation of the composition ratio in the alloy (Fe/Cu) -0.5al shows a significant effect on the mechanical properties and micro-structure. The alloy with a 60FE/40CU ratio shows the best combination in compressive strength, but has lower hardness and wear resistance. Meanwhile, the 90FE/10CU alloy has a higher hardness but a lower compressive strength. Further analysis can be done to understand more deeply about the mechanisms that affect these properties and the potential for alloy applications in the industry. The results of this study can provide valuable insights for the development of new alloys with improved mechanical properties and micro-structure.
