The phrase "alteration of material" is correct and usable in written English.
It can be used in contexts where changes or modifications to physical or digital materials are being discussed, such as in legal, academic, or technical writing.
Example: "The alteration of material in the report was necessary to ensure accuracy and compliance with the new regulations."
Alternatives: "modification of material" or "change of material".
The alteration of materials at the plate interface by aqueous fluids could form clay minerals, which could in turn contribute to a weakening of the mechanical coupling at the subducting plate interface.
That is why the change of environments might spur the alteration of genetic material, and more significantly, a better genetic material might give rise to a more advanced living system.
Taphonomic scores were established at macroscopic and microscopic (thin-section) scales by rating the degree of physical and biologically-mediated alteration of skeletal material.
This paper describes an alternate approach employing surface enhancement by low plasticity burnishing (LPB) to eliminate or reduce the surface tensile stresses necessary for corrosion fatigue failure in AA7075-T6, without alteration of environment, material or component design.
After a period of only 10 weeks, an alteration of bone material level properties was already observed in rats fed a low protein diet.
Interestingly, young adult PPARβ−/− mice exhibit a degradation of biomechanical properties without any significant changes in BMD and microarchitecture, suggesting an alteration of bone material properties.
This early degradation of bony tissue has been also previously observed in rats [ 6] and mice [ 22] and an alteration of bone material level properties could represent the initial bone degradation process in a situation of reduced protein intake.
Therefore, the authors hypothesized that an alteration of bone material level properties caused by a low protein intake could negatively influence the mechanical response of bone to cyclic loading.
In the present study, the degradation of parameters reflecting plastic behavior in rats fed a low protein diet after cyclic loading could be explained by an alteration of bone material level properties, leading potentially to an increased propensity to damage accumulation.
Ms. Jagger's art emerges from her placement and limited alteration of her materials -- a daub of red paint here, a saw cut there -- in arrangements that can seem at once decidedly monumental and surprisingly delicate, despite their roughness and heft.
