A sufficient amount of pure copper is(4 to be heated for casting a large plate in an open mold. The plate has dimensions: length = 20 in, width=10 in, and thickness =3 in. Compute the amount of heat that must be added to the metal to heat it to a temperature of 21500F for pouring. Assume that the amount of metal heated will be 10% more than what is needed to fill the mold cavity. Properties of the metal are: density=0.324 Ibm/in3, melting point = 19810F, specific heat of the metal=0.093Btu/lbm-F in the solid state and 0.090 Btu/lbm-F in the liquid .state, and heat of fusion = 80 Btu/lbm

As an Engineer describe the complete heat treatment required to produce a quenched and tempered steel microstructure contains 92% martensite and 8% Fe3C, the composition of the martensite is 1.10 C. Steel having a yield strength of at least 100000 psi. Include appropriate temperatures
Example (a) A Brinell hardness measurement is made on a ductile iron (100– 70–03, air- quenched) using a 10-mm-diameter sphere of tungsten carbide.A load of 3,000 kg produces a 3.91-mm-diameter impression in the iron surface. Calculate the BHN of this alloy. (The cor- rect units for the Brinell equation of Table 6.9 are kilograms for load and millimetres for diameters.) (b) Use Figure 6.29(b) to predict the tensile strength of this ductile iron.

Another of the steel components manufactured by michael's company is steel railway track sections. Thecomponent has a length of 120m (at a temperature of -10°C) and is to be exposed to a temperaturerange of -10°C to 55°C. In order to calculate the gaps which need to be left between the sections michael'scustomer needs to determine the maximum length which each railway track section will expand to andmichael have been asked to carry out the calculation for them. michael have also been instructed to determinethe percentage change in volume and surface area when exposed to the same initial and finaltemperatures. The customer has informed him that the cross sectional profile of the railway track isrectangular and of breadth 14cm and height 32cm. Assume the coefficient of thermal expansion ofsteel is 12x10-6 /°C. Briefly discuss the changes that occur with in the steel as a result of the change intemperature.
