The effect of multiple thermal degradation and reheat treatment cycles on the stress rupture properties of the nickel based superalloy 1N738 has been determined. These treatments simulate normal degradation in blades in service and typical commercial refurbishnient practices. Whilst reheat treatment did bring about property recovery, the effect was not long lasting: The properties of material which had only been degraded, and material which had been reheat treated and degraded, were indistinguishable. The long-term durability of the property recovery has been discussed with reference to the stability and nature of the reformed microstructure. The implications for life extension of blades and the development of modified reheat treatment schedules are also reviewed.

Life prediction tests have been performed on a polypropylene geogrid using three methods for accelerated oxidation: the wet autoclave and dry autoclave tests using pressurised oxygen, and oven ageing in normal air. The predictions from the two autoclave tests agree sufficiently well with one another, but are 40 times less than the prediction from oven ageing tests. This indicates that the autoclave and oven ageing methods cannot be regarded as equivalent for this material. The discrepancy is explained by assuming that the rate of degradation depends on oxygen pressure in a nonlinear manner, in addition to which no reduction in activation energy at lower temperatures was observed. Preference is given to the longer lifetime predicted by oven ageing. © 2012 Elsevier Ltd.
