Please help! Thank you! If one has a 1060 plain carbon steel, the carbon content is 1.06 wt% 0.60 wt.% 60 wt.% 10.6 wt.% In general, stainless steels have high content of which of these metals? Mn Mo Cr Ba A cast iron steel has carbon content compared to a steel Less More Equal Which of these elements is not considered a noble metal As Au Ti Pt As a Boeing engineer, you are designing a new Aluminum body frame...
QUESTION 6 (5+5+5+5 = 20 marks) Microalloyed steels are an important class of steels used extensively by the automotive industry. The two most important contributions to the yield strength of these alloys are the strengthening by precipitates in the form of alloy carbides and the strengthening by ferrite grain size refinement. Consider a typical Nb microalloyed alloy composition: Fe-0.1C-1Mn-0.1Nb (wt. %). These alloys are hot rolled in the austenitic condition and then air cooled from elevated temperature. Figure 1 below...
(2) Explain why stainless steel is more corrosion resistant in many environments than plain carbon steel.
1.Below are stress-strain curves for 5 steels. (a) annealed low carbon steel, (b) a steel alloy which has a DBTT of +50°C (c) 304 stainless steel (d) nearly pure coarse grained Fe Identify the modulus, yield stress, tensile strength, ductility, and toughness. Identify the amount of elastic strain at yield stress, tensile strength, point right before fracture, point right after fracture. 2000 -Low C steel, 1800 steel alloy, DBTT +50C 304 stainless pure Fe 1600 1400 1200 t 1000 800...
4. Two steels are being considered for manufacture of as-forged connecting rods. One is AISI 4340 Cr-Mo-Ni steel capable of being heat-treated to a tensile strength of 260 kpsi. The other is a plain carbon steel AISI 1040 with an attainable Sut of 113 kpsi. If each rod is to have a size giving an equivalent diameter de of 0.75 in., is there any advantage to using the alloy steel for this fatigue application?
Ou. 3 Chapters 10- 11: Phase Transformations/ Designations, Compositions and Typ Applications for Some Selected Steels (25%) Using the isothermal transformation diagram for an iron-carbon alloy of eutectoid composition 6), please, identify and name the final microstructures resulting from the two cooling curves labeled (@) and (b). (c): Draw and label on Figure 6 the cooling curve that yields the following microstructures: 50% of microstructure A (Figure 7a) and 50% of microstructure B (Figure 7b). (d) Please, provide missing information...
