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?

The company has recently expanded their product range to include some aluminium components. Toaid in the manufacturing process michael has been asked by the production manager to determine theamount of heat energy required to exactly melt 40kg of aluminium at 20° C. The melting point ofaluminium is 660 °C, its latent heat of fusion is 387 kJ/kg and its specific heat capacity is 950J/kg.K.Briefly discuss the changes that occur within the copper during this process. please solve exact and accurate with complete steps and explanation..Thank you!!!!!
Why do we use heat treatment in materials?
A steel bar is heated in a furnace until it reaches 2000oF. The blacksmith observes that it cools to 1500oF in 15 minutes. It needs to be hammered into shape before it gets within 500oF of the room temperature (100oF) before it gets too cold to be shaped properly. After pulling out the steel bar from the furnace, how long does the blacksmith have before it needs to be reheated? Assume that Newton's law of cooling is applicable.
A pipe carries hot molten lead from one part of a factory floor to another. The mass flow rate of lead is 0.05 kg/s. While trying to figure out the heat loss from the pipe, you found that over a 2-m length of he pipe the lead temperature drops from 580 C to 557.C. What is the rate at which thermal energy is being lost from the lead carrying pipe in this 2-m section? Use the property table to find out properties of lead as needed.
A copper rod and a steel rod are different in length by 5.00 cm at 0°C. The rods are warmed and cooled together. (a) Is it possible that the length difference remains constant at all temperatures? Explain. (b) If so, describe the lengths at 0°C as precisely as you can. Can you tell which rod is longer? Can you tell the lengths of the rods?
Solve this with diagram: An engine cover is made from 1 cm thick stainless steel plate (k = 14 W/m K). Air on the inside of the engine cover is heated to 340°C with a heat transfer coefficient of 7 W/m2K. Outside of the engine coverthe ambient air has a temperature of 70°C. If oil was spilled on the outside of the engine cover (ambient side), it could ignite if the surface temperature were to exceed 200°C. In this configuration, would spilled oil ignite? Use calculations to justify your answer. If a 4 mm thermal coating (k = 1.1 W/m K) was applied tothe outside of the engine, what would the outside temperature of the engine cover be reduced to? Solve it with resistors method

100 g of ice at 0º is added to 50 g of water at 20º in an insulated container.Assuming no heat is lost to the environment, what is the final temperature of themixture? How much ice melted
10.11/ A 1.5-kg specimen of a 90 wt% Pb-10 wt% Sn alloy is heated to 250°C (480°F), at which temperature it is entirely an a-phase solid solution . The alloy is to be melted to the extent that 50% of the speci- men is liquid, the remainder being the a phase. This may be accomplished either by heating the alloy or changing its composi- tion while holding the temperature con- stant. (a) To what temperature must the speci- men be heated? (b) How much tin must be added to the 1.5-kg specimen at 250°C to achieve this state?
The application of transmission gears requires superior toughness with minimal deformation, no cracks when hardening, since the part is completely transformed into bainite, and resistance to hydrogen embrittlement. Explain the most suitable heat treatment process to achieve the desired transmission gear properties.
