Which metal often does not have a well-defined yield point and which procedure is suitable to yield its strength?

I. List the importance of the impact test and limitations. II. Which material (i.e., C1045-CF, Cast Iron, AL7075-T6) was more ductile? Explain the effect of carbon content and finishing process on ductility. II. How did temperature affect the toughness of the specimens? IV. Based on these results, which material would be better to use for constructing an earthquake resistant structure? Explain. V. The following picture shows Charpy fracture surfaces of a material with different initial temperatures, after testing. Which of these figures, i.e., (a) to (e), is related to the lowest temperature? Explain. (d)

If the material is ductile, how is the failure usually specified?
