Explain what is hardenability then name some of the elements that have the greatest effect on the hardenability of steel

Which material (i.e., C1045-CF, Cast Iron, AL7075-T6) was more ductile? Explain the effect of carbon content and finishing process on ductility.

Please explain and solve the following question and do any skecthes as needed for me to understand.  explain the  distinguishing features of eutectoid and martensitic transformations in steel have? Compare and contrast them in brief

Austentitic stainless steel's are not hardenable by cold working however Austentic stainless steel's can be strengthened by heat treatment true or false?

7. Which of the following statements is suitable to describe the mechanical properties of low carbon steels and high carbon steels without cold working treatment? (a) Low carbon steels containing ferrite and pearlite phases generally have lower tensile strength than high carbon steels. (b) Low carbon steels containing cementite and pearlite phases generally have lower hardness than high carbon steels. (c) Low carbon steels containing ferrite and cementite phases generally have higher ductility and higher hardness than high carbon steels. (d) Low carbon steels are generally less stiff than aluminum alloy.

Describe the material behavior of Steel

6. What are the 4 strategies for strengthening metals? Explain in detail. Do these 4 strategies work for all metals regardless of their crystallinity? Why or why not?

Nickel-based alloys are used for gas turbine blades in aerospace engines. Briefly discuss the characteristics that make these alloys the choice for this application. Single-crystal technology is applied to nickel alloys that are used as gas turbine blades in aerospace engines. With the aid of sketches describe how a single-crystal casting can be manufactured and explain why a single-crystal casting is likely to have superior creep resistance than a directly-solidified one. Demonstrate the application of the Ten-percent Rule by calculating the approximate tensile strength and elastic modulus in the 0° direction of a carbon-fibre reinforced polymer composite if the strength and elastic moduluş in the 0° single ply are 3620 MPa and 143 GPa respectively. The lay-up sequence of the composite is [02/+45/-45/902]s.

Specify a copper alloy that requires at least 50% elongation and at least 300 MPa tensile strength.

3) (10) A 10-mm-diameter tungsten carbide sphere creates a 4.26-mm- diameter impression under a 3000-kg load. What are the yield and tensile strengths for 65-45-12 cast iron?
