22 Some patients with dementia lack cortical control of the defaecation process, tending to void formed stool following mass peristaltic movements.
Only individual voids form at low dose.
Voids form as result of vacancy migration driven by the hydrostatic stress gradient.
When the steel substrate contains Cr and Mo, fewer voids form and delamination is suppressed.
The root-cause(s) of void formation is not well understood, therefore this study is designed to understand under what conditions voids form.
Voids, often referred to as Kirkendall voids, form within the inter-diffusional zone between Cu and Sn, more specifically within the intermetallic compound Cu3Sn.
The void map (Fig. 11a) shows that the very thick voids form islands, some of which can be associated with the three pins used as reference points and with damage at the sample edge from the coring.
With increasing oxidation time voids form at the interface between oxide and Cr carbides and the amount of Cr7C3 increases at the expense of Cr3C2.
The objective is to examine how thermal stresses redistribute in response to voiding, rather than how voids form in response to stress, for gaining insights into the physics of reliability in integrated circuit devices.
When an aluminized layer is fully alloyed with the substrate iron by heating to a high temperature, voids form at the boundary between the FeAl and bcc phases in the alloyed layer.
These voids form stabilized cavitation nuclei when an acoustic field is applied in the liquid.
