Question

As the impurity concentration in solid solution of a metal is increased, the tensile strength:________.a) decreasesb) increasesc) remains unchanged

Answer 1

Increases

Step-by-step explanation:

By inhibiting the motion of dislocations by impurities in a solid solutions, is a strengthening mechanism. In solid solutions it is atomic level strengthening resulting from resistance to dislocation motion. Hence, the strength of the alloys can differ with respect to the precipitate's property. Example, the precipitate is stronger (ability to an obstacle to the dislocation motion) than the matrix and it shows an improvement of strength.
