A teacher from the Department of Materials Engineering publishes a research on the effect of adding cerium on the mechanical properties of aluminum alloy - 12% silicone

The lecturer from the Department of Materials Engineering at the University of Technology, Dr. Raad Suhail Ahmed Adnan published a scientific research entitled:

"The effect of cerium addition on the mechanical properties of aluminum alloy - 12% silicone"

"Effect of Cerium Addition on Mechanical Properties and Microstructure of Al-12%Si Alloys"

The International Journal of Developments in Science, Engineering and Technology in its No. 3 volume for the seventh year of 2019.

The aim of the study is to study the effect of adding Ce cerium element on the mechanical properties of Al-12% Si. Ce cerium element has been added in three different ratios (2%, 4%, 6%), and the alloy has been prepared by plumbing in an induction furnace with an inert argon gas Aragon was poured into a sand mold and then the castings were turned by turning. The following chemical analysis was performed by X Ray Fluorescent (XRF) for alloys and optical microscopy of the microstructure, mechanical test pressure test and Vickers Micro test for hardness done on samples.

The results of the research showed an increase in mechanical properties and a decrease in hardness, and alloys with the addition of 6% of cerium gave the best results in mechanical properties. While the subtle structure showed the silicon bush breaks with the appearance of coarse granules, with a higher percentage of Ce.
