This is an activity analyzing this science paper, but I don't understand how to answer the questions, expecially the first one.
High-entropy Alloys with High Saturation Magnetization, Electrical Resistivity and Malleability
How did the addition of Al and Si affect the magnetization of the alloy? Is this what you would expect, based on what you know about the magnetism of elements on the periodic table? Explain your answer.
Analyze the graph in Figure 2. Explain what the graph shows ,and summarize the conclusion you can draw from the graph.
In general, do transition metals or main group elements tend to have higher melting points? According to the article, the alloy tended to have a uniform structure when only Fe, Co, and Ni were included. With Al and Si, however, it had more segregation in its structure. How did the researchers speculate that the melting points of the elements affected the microstructures formed as the alloy solidified?
Explain the effect that the researchers felt the atomic size of aluminum had on their results. Does this match wwhat you know about the periodic trends of atomic size on the periodic table? Explain why or why not.
Thank you!
