Select True/False for each of the following statements regarding aluminum / aluminum alloys: (a) Aluminum alloys are generally not viable as lightweight structural materials in humid environments because they are highly susceptible to corrosion by water vapor. (b) Aluminum alloys are generally superior to pure aluminum, in terms of yield strength, because their microstructures often contain precipitate phases that strain the lattice, thereby hardening the alloy relative to pure aluminum. (c) Aluminum is not very workable at high temperatures in air, in terms of extrusion and rolling, because a non-protective oxide grows and consumes the metal, converting it to a hard and brittle ceramic. (d) Compared to most other metals, like steel, pure aluminum is very resistant to creep deformation. (e) The relatively low melting point of aluminum is often considered a significant limitation for high-temperature structural applications.

(a) Aluminum alloys are generally not viable as lightweight structural materials in humid environments because they are highly susceptible to corrosion by water vapor.

False, aluminium is not susceptible to any corrosion by the presence of water vapor.

(b) Aluminum alloys are generally superior to pure aluminum, in terms of yield strength, because their micro structures often contain precipitate phases that strain the lattice, thereby hardening the alloy relative to pure aluminum.

True.

(c) Aluminum is not very workable at high temperatures in air, in terms of extrusion and rolling, because a non-protective oxide grows and consumes the metal, converting it to a hard and brittle ceramic.

False, aluminium is stable at high temperatures and does not oxidizes.

(d) Compared to most other metals, like steel, pure aluminum is very resistant to creep deformation.

False,pure aluminium is not resistant to the creep deformation.

(e) The relatively low melting point of aluminum is often considered a significant limitation for high-temperature structural applications.

False.

In this exercise, we have to analyze the statements that deal with aluminum and its properties, thus classifying it as true or false:

A) False

B) True

C) False

D) False

E) True

Analyzing the statements we can classify them as:

(a) For this statement we can say that it is False, aluminium is not susceptible to any corrosion by the presence of water vapor.

(b) For this statement we can say that it is True.

(c) For this statement we can say that it is False, aluminium is stable at high temperatures and does not oxidizes.

(d) For this statement we can say that it is False, pure aluminium is not resistant to the creep deformation.

(e) For this statement we can say that it is True.
