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?

A.2 (i) (ii) Explain how an understanding of the creep failure mechanisms of high temperature nickel alloys has led to alloy and manufacturing developments which have resulted in an increase in the maximum operating temperature of a jet engine turbine blade. If we quench a plain carbon steel we can produce a very strong/hard and yet brittle material. Why does the quench lead to this change in properties, and what subsequent heat treatment would enable us to mostly retain the high strength whilst improving the ductility? Explain the effects of your proposed heat treatments in terms of the phase changes and microstructural features developed at each stage.
