Engineering material

The term materials engineering refers in a general way to a group of engineering specialties that are concerned with the development, production, fabrication, and use of materials in specific technologies. Some of these specialties are

Material property specifications must be written by design and material engineers to control engineering requirements and to control incoming raw material quahty. Material property requirements depend on various ia-use functional needs ia terms of electrical, mechanical, thermal, chemical, optical, and magnetic properties.

The selection of materials to be used in design dictates a basic understanding of the behavior of materials and the principles that govern such behavior. If proper design of suitable materials of construction is incorporated, the eqiiipment should deteriorate at a uniform and anticipated gradual rate, which will allow scheduled maintenance or replacement at regular inteivals. If localized forms of corrosion are characteristic of the combination of materials and environment, the materials engineer should still be able to predict the probable life of equipment, or devise an appropriate inspection schedule to preclude unexpected failures. The concepts of predictive, or at least preventive, maintenance are minimum requirements to proper materials selection. This approach to maintenance is certainly intended to minimize the possibility of unscheduled production shutdowns because of corrosion failures, with their attendant possible financial losses, hazard to personnel and equipment, and resultant environmental pollution. 

Phase diagrams are important. Whenever materials engineers have to report on the properties of a metallic alloy, or a ceramic, the first thing they do is reach for the phase diagram. It tells them what, at equilibrium, the structure of the alloy or ceramic is. The real structure may not be the equilibrium one, but equilibrium structure gives a base line from which other (non-equilibrium) structures can be inferred.

In this introductory chapter, I shall focus on the institutional beginnings of materials science, and materials engineering as well indeed, MSE became an accepted abbreviation at quite an early stage. Following an examination, in Chapter 2, of the earlier emergence of some related disciplines, the intellectual antecedents to and development of materials science in its early stages are treated in Chapter 3. The field made its first appearance in USA, and for a number of years developed only in that country. Its development elsewhere was delayed by at least a decade. 

Henceforth, materials science will normally be used as the name of the field with which this book is concerned when the context makes it particularly appropiate to include and engineering in the name, I shall use the abbreviation MSE , and occasionally I shall be discussing materials engineering by itself...

The chemical and petrochemical industries are highly capital intensive and this has two important implications for the plant designer. Before the expenditure for any plant is approved, a discounted cash flow (DCF) return on capital invested is projected (Section 9.1). The capital cost of the plant is a key factor in deciding whether the DCF return is above or below the cut-off value used by a company to judge the viability of projects. Thus, there is always strong pressure on the materials engineer not to overspecify the materials of construction. 

Conversely, however, the cost of downtime can be very high and this creates a minimum risk philosophy which runs contrary to the capital cost factor. The balance between these two forces has to be clearly stated to allow the materials engineer to operate effectively. 

The rate of a chemical reaction is influenced by pressure, temperature, concentration of reactants, kinetic factors such as agitation, and the presence of a catalyst. Since the viability of a plant depends not only on reaction efficiencies but also on the capital cost factor and the cost of maintenance, it may be more economic to alter a process variable in order that a less expensive material of construction can be used. The flexibility which the process designer has in this respect depends on how sensitive the reaction efficiency is to a change in the variable of concern to the materials engineer. 

Finally, to evaluate the membranes, analysis such as X-ray diffraction (XRD), SEM, TEM and light scattering were performed at the School of Mineral and Material Engineering, Universiti Sains Malaysia. The last part of the work, testing the produced membrane to remove emulsifier oil from domestic wastewater, was accomplished on a limited budget. An experimental rig and membrane module were required. Also the need for experimental data for the application of the supported membrane may show the real success of this project.

Unique problems were encountered in drilling wells in the Salton Sea field. The hot salt solution in the reservoir adversely affected drilling fluids and equipment, requiring the use of specially formulated drilling muds and cements developed by chemists and of special steels recommended by corrosion and materials engineers. 

A greater emphasis on surface and interfacial phenomena is needed for all chemical engineers interested in materials engineering. 

With such a broad subject area, to meet the objectives of the present publication, the general approach for this chapter has been to cover as wide a range as feasible with, where possible, emphasis made on relationships of specific effects with actual service applications. The chapter illustrates various effects of time, temperature, and fluids on long-term service durability of a range of elastomers, mainly by employing various data obtained by Materials Engineering Research Laboratories (MERE) personnel over recent years.
