Why are alloys less ductile?

Answer 1

Actually that depends on the alloy:

• iron & carbon alloys are less ductile than pure iron because the small carbon atoms position themselves between the larger iron atoms and lock them in place
• plutonium & gallium alloy is actually more ductile than pure plutonium as the gallium stabilizes the ductile delta phase at room temperature instead of the normal brittle alpha phase that usually forms at room temperature
• etc.

Answer 2

alloys are made up of several metals . therefore , due to the strong atomic linkage between atoms make the alloy more dense and hard . this harness of the material resist the alooy to become more ductile .

Answer 3

Alloys are less ductile than pure metals because the addition of different elements creates grain boundaries that impede the movement of dislocations, making it more difficult for the material to deform plastically. The presence of different elements can also introduce stress concentrations, leading to premature failure.

Answer 4

A pure metal is more ductile as Gold, Silver, Copper and Iron are more ductile than their alloys.
