Ct scan porosity
WebFor instance, the porosity values calculated from CT images with resolutions of 224 nm and 63 nm were 20.4% and 27.8%, respectively, inferring that low-resolution scanning underestimates porosity (Iacoviello et al., 2024). Moreover, nano-CT could not resolve microscopic pores that are widely distributed in shales (<50 nm). WebApr 9, 2015 · April 9, 2015. Casting is a process of pouring a liquid, typically metal or plastic, into a mold to produce a solid part. That’s the theory, but in fact “solid” parts often contain voids or inclusions, which may or may not impact the performance of the finished part. Porosity can be bad, meaning that the resulting part will not perform as ...
