The Al-Cu phase diagram is given below. Assume equilibrium conditions when
answering the following questions.
a) Sketch the expected microstructure at each temperature in the circles provided on the
phase diagram. Indicate the identity of any
HW05 Solution
(a) Thoria is a compound . Since the particles are hard, the dislocations
cannot cut through them. They have to bow around them. Therefore the uniaxial
yield strength of the material is increased.
(b) Silicon has covalent bonding, while sil
HW07 Solution
The fracture strength of an object also depends on the Youngs modulus
and Poissons ratio of the material.
So even if the toughness and geometry are similar, two different materials
can lead to very different strengths.
