Why is the mechanical strength of the HAZ next to the fusion line of a non-heat treatable
aluminum alloy much lower than that of the base metal?
Why does the mechanical strength of the HAZ of a non-heat treatable aluminum alloy
increase with distance from the fusion line?

Heat of Vaporization and Heat of Fusion
Learning Goal:
To calculate the total energy required to convert a solid to a
gas using heat capacity, heat of fusion, and heat of
vaporization.
The amount of heat required to melt one mole of a solid is called
the heat of fusion (ΔHfus). The amount of heat
required to vaporize (boil) one mole of a liquid is called the
heat of vaporization (ΔHvap). The heat of fusion
and the heat of vaporization...

Water's heat of fusion is 80. cal/g , its specific heat is
1.0calg⋅∘C, and its heat of vaporization is 540 cal/g . A canister
is filled with 340 g of ice and 100. g of liquid water, both at 0
∘C . The canister is placed in an oven until all the H2O has boiled
off and the canister is empty. How much energy in calories was
absorbed? Express your answer to two significant figures and
include the appropriate units
