software component stress analysis. The authors deem both castings should be required for effective alloy conversion assessments.
If the U328 alloy is considered for future casting component validations the TSR and solution treatment temperatures should be elevated between the 515 to 525C (959-977F) range. At this elevated solution temperature range the ther- mal breakdown of sand is quicker, and saturation of α-Al dendrites is enhanced over the 505C (941F) solution treat- ment.29
F) solution treat- treat- Consequently, artificial aging strengthening will be more efficient. Acknowledgements
