"material aging" is correct and usable in written English.
It refers to the process of a material deteriorating or becoming worn over time. Example: The building's facade showed signs of material aging, with cracks appearing in the concrete and rust starting to form on the metal parts.
Aging and fatigue effects are separately analysed showing that part of the cracking in thermal cycling tests is related to material aging during the high temperature part of the cycle.
Material aging ("thermal fatigue") in nuclear power plant piping systems due to thermal fluctuations has been identified as a high ranking safety issue (NEA/CSNI/R(2007 13 (2008) [19]).
Conversely, the recovered MSWI BA cannot be recommended to be used in the base layers as such, even though its stiffness properties increased over time due to material aging and changes in moisture content.
When these components operate in the ductile-to-brittle transition (DBTT) regime of the material (due to irradiation embrittlement and other material aging and degradation mechanisms taking place), the two mechanisms that compete with each other in the failure process are: ductile and cleavage fracture.
The three adsorbents were tested for material aging by using the same adsorbent over five adsorption desorption cycles at 25 °C and at 1 bar.
Delamination and cracks are fatigue failures of the gliding surfaces due to a combination of material aging and high stress concentration.
Preliminary catalyst screening at 140 °C showed a FUR selectivity maxima for the material aged at 100 °C.
So far, the solar dish has shown to be a very versatile facility for testing materials aging under high solar radiation densities.
Nondestructive methods for directly evaluating the mechanical properties are required for the success of any materials aging and life management program.
As dental prosthesis materials, aging abrasion of G/Z and Y-TZP therefore increased the probability for biofilm formation.
As materials aged and tastes changed, however, its vibrancy diminished.
