Consider the following three alloys from the Al-Cu system (see Al-Cu Phase Diagram): Pure Aluminum, 3wt%Cu-97wt%Al, and 8wt%Cu-92wt%Al. • Which of these alloys is the best candidate for Age Hardening? Why?• Which of these alloys is the worst candidate forAge Hardening? Why?
The tempering of ferrous martensite and the precipitation hardening of Al alloys have much in common, even though in one case the objective is to soften the material and in the other case it is to harden it: (a) For both the Al alloy and for ferrous martensite plot schematically the evolution of the following parameters as a function of aging/tempering time: 1. the expected evolution of the yield stress 2. the expected evolution of the mean precipitate size 3....

The true stress-true strain of several Al alloys that can be used in manufacturing a component in an aircraft is given by g = K €", where K is a constant and n the strain- hardening exponent. The manufacturing process involves sheet forming. During use, the component will be subjected to the following stress tensor: 10 20 0 20 -20 0 00-5 MPa The following information regarding available materials Alloy allowable Tallowable Cost/part Density (g/ce) (MPa tension (MPa) 3.05 0.22...
Magnesium-aluminum alloys are commonly used in aircraft construction. When treated with acid, both metals react to form hydrogen gas, as shown in the unbalanced chemical equations below. A 1.000 g sample of alloy produces 0.107 g of H2 (g) when reacted with excess HCl (aq). What is the percent composition by mass of Al in the alloy? Al (s) + HCl (aq) à AlCl3 (aq) + H2 (g) Mg (s) + HCl (aq) à MgCl2 (aq) + H2 (g)
Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...
When water freezes, it expands about 9 percent. What would be the pressure increase inside your automobile engine block if the water in there froze? The bulk modulusof ice is 2.0 ? 109 N/m2, and 1 ATM = 105 N/m2.
24.1 kJ of energy is lost by a 251 g Al block. If the block is initially at 125.0°C what will be its final T in °C? (sAl = 0.902 J g-1 °C-1)
(12 points) Two alloys A and B are being used to manufacture a certain steel product. An experiment needs to be designed to compare the two in terms of maximum load capacity in tons. This is the maximum that can be tolerated without breaking. It is known that the two standard deviations in load capacity are equal at 10 tons each. An experiment is conducted in which 36 specimens of each alloy (A and B) are tested and the results...
Question 33. Heat treatments are often performed on metal alloys in order to control their properties. (a) Briefly describe how heat treatments can affect the strength and ductility of metals. (2 Marks) (b) Wrought aluminium alloys often contain alloy constituents to improve various properties. 6xxx series aluminium alloys contain Magnesium and Silicon, which if present in appropriate concentrations, can form a hard intermetallic phase Mg2Si in the microstructure. Describe a suitable precipitation hardening heat treatment process for containing 0.5% Mg2Si...
