Question

Of the following alloys pick the one(s) that may be strengthened by heat treatment cold work or both.

a. AZ31B magnesium
b. 6061 aluminum
c. C17200beryllium copper
d. R50500 titanium
e. 304 stainless steel
f. 6150 steel
g. C51000 phosphor bronze
h. lead

Answer 1

Some of the alloys that can be strengthened by heat treatment, cold work, or both are AZ31B magnesium, 6061 aluminum, C17200 beryllium copper, 304 stainless steel, 6150 steel, and C51000 phosphor bronze.

Step-by-step explanation:

Of the alloys listed, the ones that may be strengthened by heat treatment, cold work, or both are:

1. AZ31B magnesium
2. 6061 aluminum
3. C17200 beryllium copper
4. 304 stainless steel
5. 6150 steel
6. C51000 phosphor bronze

These alloys can undergo heat treatment processes like annealing, quenching, and tempering to improve their mechanical properties.

Additionally, they can be strengthened through cold working methods such as rolling, forging, and extrusion.
