The tensile strength for cold-rolled magnesium alloy AZ31B plate is approximately 160 MPa for specimens tested either parallel or perpendicular to the rolling direction. When similarly oriented specimens are compressed, the yield strength is only 90 MPa. Why? (Hint: Consider the possible deformation mechanisms available in the magnesium alloy and any crystallographic texture that might exist in the wrought plate.)

Question
The tensile strength for cold-rolled magnesium alloy
AZ31B plate is approximately 160 MPa for specimens tested
either parallel or perpendicular to the rolling direction.
When similarly oriented specimens are compressed, the
yield strength is only 90 MPa. Why? (Hint: Consider the
possible deformation
in the wrought plate.)
Expert Solution
Step 1
The cold-rolled aluminum has high tensile strength The material having large tensile strength undergoes large plastic deformation whereas the yield strength is less In compression The reason that the crystallographic texture.
