Biomaterials Question 1 Would a perfect metallic crystal be

Biomaterials Question:

1. Would a perfect metallic crystal be brittle or ductile? Why?
2. During the normal function of a femoral stem component of a hip joint implant, would you expect slip to occur?

Solution

1.
The crystalline structure is brittle
to make it ductile it might would be melted and allow to cool slowly.

2.
We do not expect slip to occur within the hip stem due to the fact slip is plastic deformation, and if plastic deformation occurs, then the hip stem would lose its shape and function over time.
Materials that undergo plastic deformation below the load-bearing situations of the implant are typically not selected for this.
