Explain the basic principle of the following steel making process: 1. Bessemer process 2. Open-heart process 3. Electric Arc process

How did temperature affect the toughness of C1045-CF, Cast Iron, and AL7075-T6?

What is the marcosopic structure of metallic in low carbon and then high carbon  steels .

Rank the six microstructures of steel in general order of least ductile. (bainite, coarse pearlite, martensite, spheroidite, tempered matensite)

On what is the Design of a member for strength-based?

A material is required as heating elements for an electrical resistance furnace for heat treating steels. Make and list appropriate assumptions for temperature and furnace environment. List what you would judge to be the design-limiting properties. Name three candidate heating element materials.

1. Please draw a typical tensile test curve for low carbon steels and mark the four stages and list their names (use critical points on the curve to help you identify the start and end points of the four stages). 2. Show the yield, ultimate tensile strength and fracture points, as well as yield and ultimate tensile strength on the curve. 3. Please draw the load and unload curve for a stress level causing the low carbon steels to experience elastic deformation only. 4. Please draw the load and unload curve for a stress level causing the low carbon steel to experience permerment deformation, and identify both elastic and plastic strain on the drawing after unloading.

What property of a metal describes its ability to be easily drawn into a wire but not rolled into a sheet without splitting?

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

What is the composition (wt% C) of a steel with AISI designation 1090? .Would this be considered a low, medium, or high carbon steel? (circle one)
