Answer with true (T) or false (F), corrects the wrong phrases, and gives short reason(s) for correct and corrected statements: 1- Normalized steels have better strength and toughness as compared to annealed steels. 2- Ferrous alloys are most important and widely used in comparison to any other metals. 3- Metals of BCC crystal structure are denser than metals of FCC structure. 4- Hypo-eutectoid steels fully annealed by heating to about 30°C above the upper critical temperature. 5- The full martensite microstructure can be obtained by cooling the steels with any cooling rate. 6- There is a large volume expansion when martensite forms from austenite.

As an R&D engineer, your input is requested to design an enhanced device that will be permanently implanted to repair the load-bearing function of a joint. Details on the candidate metals are presented here: Material SS 316 type Pure Ti Density (p) Yield stress (g/cm³) (MPa) 8 4.5 Ti6A14V 4 (F136) 190 140 795 Maximum elongation (%) 40 15 10 Elastic modulus (GPa) 190 110 114 Lo Shess leve O What force can each of the materials carry without permanent deformation? Which one offers better properties as a load-bearing implant? Explain. Describe the primary consequences of choosing the wrong material; consider in your answer the effect of density, yield stress, elongation, and Young's modulus on the implant's performance.
