In the carburizing process the steel piece was exposed, at an elevated temperature (900 °C), to an atmosphere rich in a hydrocarbon gas, such as methane CH Surface concentration of carbon is to be maintained at 1.18 wt%. Determine the time (in hours) necessary to achieve a carbon content of 0 68 wt% at a position 0.8 mm below the surface. Initial carbon concentration is 0 18 wt% Take the diffusion coefficient for carbon in iron at 900°C = 1.0...

Bonus Problem (worth 5 extra points.) You must show all your work to receive credit! 26. You are asked to improve the hardness (and strength) of a steel sample by "carburization" process. The initial carbon content (co) of the sample is 0.2 wt %. You are using a carbon rich environment (hydro- carbon gas) to set the surface-carbon content (c) at 1.0 wt %. Using the Figure 5.11, calculate the required carburization temperature to reach a carbon content of 0.4...

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
