The phrase "altered materials" is correct and usable in written English.
It can be used when referring to materials that have been changed or modified in some way, often in contexts like art, science, or manufacturing.
Example: "The artist used altered materials to create a unique texture in her sculpture."
Alternatives: "modified materials" or "transformed materials."
The failure modelled was relatively small (volume of 0.21 km3), and would have mostly involved hydrothermally altered materials with some fresh rock mass.
The Na/Al and Si/Al ratios decreased from unaltered, to edge, to altered grain sections in the mixed conifer sites, whereas the element ratios of the desert scrub system were similar between unaltered and edge grain sections, and only exhibited significant decreases in Na/Al and Si/Al ratios between edge and altered materials.
At a minimum, we can consider that resistive body R2 corresponds to weakly altered materials.
Julia manipulates a variety of found and altered materials in her work, combining contemporary sculptural and traditional craft techniques.
The majority of the ash is intensively to partly altered materials as same as the ash of the 2008 and 2010 phreatic events (Suzuki et al., 2013a).
Altered materials properties of the tumor ECM are clinically relevant as they promote tumor malignancy via direct effects on tumor cells [ 8] and indirectly by enhancing the formation of new blood vessels (angiogenesis) [ 4, 9– 13].
The amount of altered material is the highest through the whole activity, probably because altered parts of the volcanic edifice were destroyed by the early eruptions.
During the weathering process the translocation of disintegrated or altered material occurs within the immediate vicinity of the rock exposure, but the rock mass remains in situ.
Using the AFM topographic data we were able to quantify the FN nanofiber volume pre-release and post-release to determine if the large deformation altered material volume.
The results presented identify altered material properties and improved cellular interaction on Ti30Ta nanotubes as compared to Ti30 Ta alloy.
Subsurface microhardness studies were also done to assess the depth of compression, altered material zone and correlate fatigue life with surface roughness and surface hardness.
