The data is supported by explanations of how to make use of the data in real-world engineering contexts. High heat environments are common in automotive, oil and gas, household appliances, coatings, space and aeronautics and many more end uses. As a result, thermal stability data are critically important to engineers designing parts particularly that replace metals, work th UR - http://148.231.10.114:2048/login?url=http://www.sciencedirect.com/science/book/9780323221085 ER -
