... plasticizer contents of 28 and 25%, respectively. The results also showed that the reference material, containing the trimellitate-based plasticizer, exhibited superior thermal resistance relative to the failed material, containing the adipate-based material. This was indicated by the elevated temperature...

.... There was no question that the material failed as a result of exfoliation corrosion, so an investigation was undertaken, centered around the study of thermal treatments that would increase the exfoliation resistance and still develop the required 448 MPa (65 ksi) yield strength. The results of the study concluded...
