The phrase "aging of materials" is correct and usable in written English.
It can be used in contexts discussing the deterioration or changes in properties of materials over time, often in fields like engineering, materials science, or art conservation.
Example: "The aging of materials used in the construction of the bridge has raised concerns about its structural integrity."
Alternatives: "degradation of materials" or "deterioration of materials".
Aging of materials can have significant effects on the structural performance of highway bridges.
The supercomputer at the lab, expected to be completed by 2004, will use its 130,000 processors to simulate physical phenomena like the aging of materials, fires and explosions, potentially useful in safety and security planning.
While aging of materials was clearly observed in a reduction of denitrification by 60 70% during the experiment, systems still worked very well until the end of the experiment.
Ageing of materials or pre-treatment through leaching is needed prior to their use in construction to avoid peak concentrations.
Therefore, a better understanding of the processes contributing to thermal aging of these materials is of crucial importance.
In the study, both Optim and Pursil 35 were exposed in laboratory tests to water and heating techniques aimed to accelerate aging of the materials.
Photoirradiation in an oxygen ambient causes photo-oxidation at the surface and thus accelerates aging of the material.
"Traditionally, scientific analysis has been able to distinguish authenticity by the nature and age of materials," she said.
However, due to the ageing of materials and to aggressive environmental actions which cause deterioration, the response of these structures, just like others, changes over time, resulting in a loss of performance.
In other circumstances, time trend effects can be caused by learning effects of the test subjects in behavioural and life sciences, heating or ageing of material in prototype experiments, etc.
Using radiocarbon dating, which measures the age of material based on how many of the carbon atoms in them have undergone radioactive decay, he estimated that a bit of burned bear bone found on one of the structures was about 47,600 years old — making it almost as old as modern humans' presence in Europe.
