Question 1
You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt-
chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows...
A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some
magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded).
Q1F: How would the "new alloy" material (with different properties as shown below) behave, assuming it has the same initial
diameter (10mm) and applied load (F) in the tensile test? That is, would it experience plastic deformation (yield) under the
conditions of this problem?
What are some possible defects in drawn sheet-metal parts?
In blanking of a circular sheet-metal part, is the clearance applied to the punch diameter or the die
diameter?
What is martensite?
Based on the TTT curve, what is it that should be avoided during martensitic process?
What is the main condition for strengthening an alloy by precipitation?
What is the advantage of nitriding? Select all correct answers.
Some complex components can be nitride without difficulty.
Better wear resistance.
Better fatigue resistance.
The cheapest method of case hardening.
What is the correct definition of plastic deformation?
The behavior of a material when its size changes by the addition of heat.
The behavior of a material that deforms under load and returns to its original shape when the load is removed.
Deformation caused by cleavage, where the material is actually pulled apart across atomic planes within the crystals or along the grain boundaries.
The behavior of a material that deforms under load and does not fully return to its original shape when the load is removed.
