Literature vs test: Al 356 alloying

In summary, the conversation discusses the Young's Modulus of Al356 alloy and the discrepancies between the literature value of ~70GPa and the maximum values of 4-5GPa obtained in experiments. The speaker suspects that the MTS testing machines may not be calibrated properly.

Hi guys, first post here, since I can't find any literature I might as well try a forum. Literature states that Al356 alloy has a Young's Modulus of ~70GPa, of course it will change with tempering and aging differences, but it should be around there. My experiments at school are only yielding around 4-5GPa as maximum Young's Modulus, where the lower values can go as low as 1.5GPa. Does anyone know what is going on, if this is a common occurance or maybe our MTS testing machines just aren't calibrated right?

Thanks in advance.

Hi shaneinhisroo, welcome to PF. The Young's modulus isn't going to change much even with temperature and processing. Sounds like your machine (or analysis approach?) is at fault.
 

Related to Literature vs test: Al 356 alloying

What is the difference between literature and test for Al 356 alloying?

The main difference between literature and test for Al 356 alloying is the source of information. Literature refers to published materials such as books, articles, and journals, while test refers to experimental data and results obtained through testing methods.

Which is more reliable, literature or test for Al 356 alloying?

Both literature and test have their own strengths and limitations. Literature provides a comprehensive understanding of the theoretical concepts and previous research on Al 356 alloying, while test provides direct and empirical evidence. Therefore, a combination of both literature and test is recommended for a more reliable analysis.

Can literature replace test in studying Al 356 alloying?

No, literature cannot replace test in studying Al 356 alloying. While literature can provide a theoretical understanding, test is crucial for verifying and validating the theories and obtaining precise data for analysis.

What are the advantages of using literature in studying Al 356 alloying?

Using literature in studying Al 356 alloying allows researchers to gain a thorough understanding of the subject and its history, identify knowledge gaps, and develop hypotheses for further testing. It also provides a foundation for designing experiments and interpreting results.

What are the advantages of using test in studying Al 356 alloying?

Test allows researchers to obtain empirical data and results, which can be used to validate or refute theories and hypotheses. It also provides precise and quantitative data for analysis, allowing for a more accurate assessment of Al 356 alloying properties and behaviors.
