This article focuses on the cooling process and related transformation behavior of steel wires during patenting to identify a physical metallurgical basis for the development of nontoxic alternatives to molten lead for wire patenting. It describes the materials required, the procedures, and the results of cooling curve analysis. The article schematically summarizes the cooling behaviors of the various cooling media and the microstructure of the pearlite transformation in a lead bath.

Cooling towers are designed to remove heat from water in an induction system and dissipate it into the atmosphere. This article provides information on closed-loop recirculating water systems of an induction system to cool the power supply. It focuses on various types of cooling towers, namely, air-cooled heat exchangers, air-cooled heat exchangers with trim cooler, closed-circuit evaporative cooling towers, and open evaporative cooling towers. The article discusses the importance of their placement or positioning to reduce the chances of air recirculation, and concludes with a discussion on refrigerant chillers.

Thermal analysis is a classical method of determining phase diagrams and can be used to analyze the deviation from solidification under equilibrium conditions. This article discusses the use of thermal analysis in industrial processes and in research. It describes the theoretical basis of simplified and differential thermal analysis. Techniques for determining liquidus and solidus temperatures using cooling curves are also discussed.

In this article, a metallurgical overview of the hardening process is provided. This overview is followed by the methodology involved in obtaining cooling curves, the currently accepted standardized methods of testing, and the use of newer methods of cooling curve data interpretation that describe the quenching process.
