| | The Cyclic Oxidation of Fe-20Cr-4Al Alloys with Small Additions of Rare Earth Elements (Y, Pr, Gd or Ho) (Site not responding. Last check: 2007-10-23) |
 | | The cyclic oxidation behavior of Fe-20Cr-4Al, Fe-20Cr-4Al-(0.07, 0.43)Y, Fe-20Cr-4Al-(0.06, 0.45)Pr, Fe-20Cr-4Al(0.01, 0.39)Gd and Fe-20Cr-4Al-(0.03, 0.43)Ho alloys was studied in oxygen. |
 | | Cyclic oxi dation testing consisted of a 5 min exposure at 1250°C followed by a minimum cooling time of 20 min, dur ing which the specimen temperature reached 46°C. This oxidation-cooling cycle was repeated up to 10 times. |
 | | The spalling o f surface oxide on the Fe-20Cr-4Al alloys with rare earths was not observed after 10 cyles of cyclic oxidation. |
