The Effects of Hot Isostatic Pressing of Platinum Alloy Castings on Mechanical Properties and Microstructures

The effects of hot isostatic pressing (HIP) on castings produced in a variety of platinum alloys was investigated. A number of benefits were observed, including a reduction in porosity and improvements to the microstructure and mechanical properties. Differences in the response to HIP of individual...

Zusammenfassung:The effects of hot isostatic pressing (HIP) on castings produced in a variety of platinum alloys was investigated. A number of benefits were observed, including a reduction in porosity and improvements to the microstructure and mechanical properties. Differences in the response to HIP of individual alloys is evaluated as well as some inherent limitations of the HIP process.
