The phrase "aged material" is correct and usable in written English.
It can be used to refer to items or documents that have been in existence for a significant period of time, often implying that they may have historical or archival value.
Example: "The library has a special section dedicated to aged material, where researchers can find rare books and manuscripts."
Alternatives: "old documents" or "historical materials".
Rectangular samples of dimensions 50 × 20 × 8 mm3 were machined from the aged material.
SEM images confirmed that this change led to a morphology change of the aged material.
Results from creep crack growth tests for similarly aged material reduced incubation time and accelerated the crack growth rate.
The fracture mode transitions from highly ductile, microvoid coalescence in new material to a mixed mode of shallow dimples and inclusion-induced voids in the naturally aged material.
A comparison with isothermally aged material showed that coarsening of M23C6 carbides is accelerated by the strain, while the effect of strain on VN precipitates is insignificant.
The extent of stress enhancement is determined by comparison of measurements from creep tested material with those from stress-free aged material.
Dynamical mechanical thermal analysis results on hydrothermally aged materials indicated the occurrence of progressive segregation effects with the formation of regions with different cross-linking degrees.
The actual threshold of abundance is probably lower than this limit, since there were no signs of changes in reactivity of aged materials exposed to oxygen for one month.[60].[60]
The higher arsenic loadings are likely due to a coprecipitation mechanism and the fact that freshly precipitated ferric hydroxides have higher arsenic adsorption capacities than aged materials.
Rarely requested or otherwise aging material, these experts agreed, must be removed to a remote storage area, far from the public eye.
The deformation behaviour of both flat and round specimens of a dynamically strain ageing material was simulated, utilizing constitutive parameters for an Al Mg Si alloy.
