Quenching is often used in the manufacturing and/or heat
treatment of magnesium alloys, aluminium alloys
and steels.
Explain why quenching is used for each of these
three metals, and explain how this benefits the final
mechanical properties.
explain why we are doing a solution treatment before
aging treatment for alloys. b) describe the microstructure
difference between aged alloys with and without solution
treatment+quenching.
Which metal hardening mechanism is reversible by annealing (heat
treatment) of the material?
You are given an alpha-titanium alloy to process into a turbine
blade. Based on the fact that the alloy has an HCP crystal
structure, what general processing technique would you consider for
the processing of the turbine blade? Explain your choice.
Metal hydrides are metal alloys that can store significant
quantities of hydrogen in their atomic lattice. For this reason,
they are considered potentially attractive for the on-board storage
of hydrogen for hydrogen fuel cell vehicles. A certain metal
hydride alloy can store 2 wt% hydrogen and has a density (including
the hydrogen) of 12 g?cm3. Treating hydrogen as an ideal gas, what
pressure would beneeded tocompressgaseous hydrogen
tothesameequivalent concentration thatit attains when absorbed in
the metal hydride?
