h-BN inclusion in a β-Si3N4 grain
The micrograph shows h-BN inclusion (precipitate) in a β-Si3N4 grain (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Such
Birefringence in a film of polyethylene
The colours in the image are the result of birefringence and relate to the residual stress in the film. The colour is generally uniform (with some contrast where an additional thickness of film exists or where wrinkling has resulted in a different apparent thickness). This is indicative of both a uniform film thickness and of the uniformity of the drawing process used to make the film. In the region of the tear, however, the colours indicate strain-induced orientation: because the material is ab
Interface boundary between h-BN and Si3N4 grains
The micrograph shows a regularly stepped interface boundary between h-BN (precipitate) and Si3N4 grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and
Misoriented interphase boundary between h-BN and SiC grains
The micrograph shows misoriented interphase boundary between h-BN (precipitate) and SiC grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react wit
This module seeks to explore the definition and nature of state crime in criminological and political discourse.
