Carburizing on Non-Ferrous Alloys

Assertion (A): Carburizing is done on non-ferrous alloys to increase the surface hardness.

Reason (R): Precipitation hardening of non-ferrous alloys involves solution heat treatment followed by precipitation heat treatment.

Explanation:

Carburizing is a process of introducing carbon into the surface layer of a material to increase its surface hardness. It is commonly used on ferrous alloys, but it can also be done on non-ferrous alloys such as aluminum, titanium, and magnesium.

However, Reason (R) is not a correct explanation for Assertion (A) because precipitation hardening of non-ferrous alloys does not involve carburizing. Precipitation hardening is a heat treatment process used to increase the strength and hardness of non-ferrous alloys such as aluminum and titanium. It involves solution heat treatment followed by quenching and aging. During the aging process, small particles called precipitates form in the alloy, which increase its strength and hardness.

Therefore, the correct answer is option D - Assertion (A) is false, but Reason (R) is true.
