Lämpökäyrä

Lämpökäyrä, often translated as temperature curve or thermogram, is a graphical representation of temperature changes over time. It is a fundamental tool used in various scientific and industrial fields to visualize and analyze thermal processes. The x-axis typically represents time, while the y-axis denotes temperature. The shape and characteristics of the curve provide valuable information about the substance or system being studied.

In metallurgy, lämpökäyrä is used to understand phase transformations during heating and cooling processes. For example, it can reveal the temperatures at which a metal melts, solidifies, or undergoes structural changes. This information is crucial for controlling material properties and ensuring product quality. In materials science, lämpökäyrä can illustrate the thermal decomposition of polymers or the curing process of resins.

Beyond industrial applications, lämpökäyrä finds use in biology and medicine. For instance, it can depict the temperature fluctuations in a biological sample or monitor the fever patterns of a patient. In meteorology, temperature curves are used to track diurnal and seasonal temperature variations. The analysis of a lämpökäyrä often involves identifying key points such as maximum and minimum temperatures, transition points, and the rate of temperature change.
