High-temperature exposure of materials occurs in many applications such as power plants (coal, oil, natural gas, and nuclear), land-based gas turbine and diesel engines, gas turbine engines for aircraft, marine gas turbine engines for shipboard use, waste incineration, high-temperature fuel cells, and missile components. This article discusses high-temperature corrosion in boilers, diesel engines, gas turbines, and waste incinerators. Boilers are affected by stress rupture failures, waterside corrosion failures, fireside corrosion failures, and environmental cracking failures. Contamination of combustion fuel in diesel engines can cause high-temperature corrosion. Gas turbine engines are affected by hot corrosion. Refractory-lined incinerators and alloy-lined incinerators are discussed. The article provides case studies for each component failure.

The article also provides information on the applications of PM hot isostatic pressing in the oil and gas industry.

Grinding is an extremely complex process that requires the consideration of a number of elements in order to make a reasonably adroit initial selection of a fluid or fluids for a manufacturing plant. In addition, the disposal of grinding wastes must meet the minimum requirements as recommended by the federal Environmental Protection Agency (EPA) and Resource Conservation and Recovery Act (RCRA) regulations. This article explains the selection considerations of such fluids, as well as the applications and environmental issues related to the grinding processes.
