Brittle Dune Buggy Parts A mechanic who was building a lightweight dune buggy needed some high-strength aluminum parts.  Since he had access to a heat-treating furnace, he decided to do the solution heat-treating and aging process himself.  He obtained 2024 aluminum bars and made the parts.  Then her heat treated the part in a furnace to 1200 deg F., quenched them, and allowed them to age naturally.  He noticed they had small blisters over their surfaces and when he began to hammer one in place, it broke in two places.  What did he do wrong?  Could the parts be salvaged in any way?

Strengthening of Alloys

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processes. Due to the movement of these dislocations, the metals are plastically deformed.
