Embodiments relate to a system for predicting thermodynamic phase of a material. The system includes a phase diagram image scanning processing module configured to scan a binary phase diagram for each material to be used as a component of a high-entropy alloy (HEA). The system includes a feature computation processing module configured to generate a primary feature and an adaptive feature. The primary feature is representative of a probability that the HEA will exhibit a solid solution phase and/or an intermetallic phase. The adaptive feature is representative of a factor favoring formation of a desired intermetallic HEA phase. The system includes a prediction module configured to encode the primary feature and/or the adaptive feature with thermodynamic data associated with formation of HEA alloy phases to provide an output representation of the HEA alloy phases for a material under analysis.

Methods for performing seal validation with a chemical pre-treatment are provided. One such method includes establishing an Arrhenius relationship between a material property response of a material exposed to a test fluid based on experimental results of testing a plurality of material samples made of the material across multiple temperatures. The method also includes determining, based on the Arrhenius relationship, a pre-treatment time and a pre-treatment temperature that approximates a seal end-of-life condition. The method further includes pre-treating a seal by exposing the seal to the test fluid at the determined pre-treatment temperature for the determined pre-treatment time, the seal having at least in part a same material composition as the plurality of material samples, and after pre-treating the seal, performing one or more validation tests on the pre-treated seal.

Embodiments herein relate to articles and methods for detecting heating patterns within model food compositions containing irreversible thermochromic ink, and for creating multi-dimensional temperature distribution profiles within a packaged model food composition. In an embodiment, a packaged model food composition for thermal testing is included. The packaged model food composition can include a package and a model food composition disposed in the package. The model food composition can include a model food material that shares processing characteristics with a target food material and 0.05 wt. % to 20 wt. % of one or more irreversible thermochromic inks. The irreversible thermochromic inks can exhibit a variable change in at least one color parameter in response to temperature change across a selected temperature range. Other embodiments are also included herein.

A system includes a downhole tool having a housing and a passage extending through the housing, where the passage includes an inlet configured to receive a flow of a wellbore fluid and an outlet configured to discharge the flow of the wellbore fluid. The downhole tool includes a heating element configured to heat the flow of the wellbore fluid and to enable the flow of the wellbore fluid to transition to a single-phase fluid flow within the passage. The downhole tool includes a phase composition sensor positioned adjacent the passage and configured to provide feedback indicative of formation of the single-phase fluid flow. The system includes a controller configured to monitor a power consumption of the heating element and to determine an enthalpy of the wellbore fluid based in part on the power consumption and the feedback from the phase composition sensor.

A system for detecting contamination in a two-phase immersion cooling system based on temperature differences between component surface temperature and fluid temperature, a previous component surface temperature and a present component surface temperature and a component surface temperature and a component surface temperature threshold value. Large differences between the component surface temperature and the fluid temperature or between the component surface temperature and a previous component surface temperature or a component surface temperature exceeding a component surface temperature threshold value may indicate contaminants in the fluid that are inhibiting the ability for the component to effectively transfer heat to the fluid. A temperature monitoring system may monitor the temperatures and communicate with a service system to apply corrective measures before the residue can cause significant damage to an information handling system.
