Flashcards in Test 2 Deck (19)
_______ cooling of austenite results in pearlite
Bainite has __________ particles of cementite
Adding zinc to copper to form a substitution also solid solution would cause the crystal lattice to be distorted, which would _________ the yield strength
Nonpermanent deformation recovered upon release of a mechanical stress is called _________
Impose compressive surface stresses will prevent cracks from growing (T or F)
Cleavage is a ___________ type of brittle fracture
In the diagram above, what is the point corresponding to 61.9% wt. Sn called?
When two elements are completely miscible into each other, the resulting phase diagram is called?
Which of the following has the highest carbon content?
Can pearlite be a pro-eutectoid phase (Y or N)
Which curve is most probably for elastomer
Curve with lowest slope. Elastomers typically show a very elastic behavior with low tensile strength
Which materials do you expect to fail in brittle fashion?
Two highest slopes. Have a very low % elongation and reaches a high tensile stress before fracturing
Which material is toughest and why?
Material with squiggle. Has the largest area beneath the curve
Which material is stiffest?
Highest slope. Young’s modulus is greatest on the graph because it has the steepest slope
