Structural features typically associated with normal Galaxea fascicularis septa, such as acicular
and fusiform crystals and well-defined fasciculi (Fig.
erinacea), such as narrow acicular
leaf shape and maximum leaf involution, in combination with schlerenchyma in an abaxial shield (Fig.
To do this, the used acicular
PCC was coated with stearic acid with a concentration of 1.6 wt%.
The presence of acicular
ferrite (AF) with fine grains, which provides maximum resistance to crack propagation, was observed in the processes investigated.
Chrysocolla pseudomorphs (to 5 mm) after a bladed or acicular
mineral (malachite?) and a mineral which formed small (to 2 mm) lenticular crystals were also found in an isolated occurrence in a pillar.
Formation (in the second case) of acicular
[Me.sub.6]C carbides at the base--seam boundary exerts effect of incision in the tests and causes reduction of the BJ plasticity.
The technology employs two types of super-fine magnetic particles, both tens of nanometers in scale: Acicular
Ferromagnetic Alloy particle and Tabular Ferro-magnetic Hexagonal Barium Ferrite particle.
The optimum average particle size for opacity for acicular
aragonitic PCC is 0.4-0.557[micro]m.
These are clusters of acicular
crystals that form fasciculi and spindle-shaped crystals referred to as fusiform crystals.
The microstructures of the Q690 BM were mainly of lath bainite, with abundant acicular
ferrite island groups, as presented in Figure 1(c).
To analyze possible variations in the crystalline morphology with the introduction of the acicular
nanofiller, an AFM study was performed on PE and all the nanocomposites prepared.
Investigation  shows that resistance of welded joint to tension stresses and dynamic loads is higher when microstructure of the weld contains acicular
Epidote from the Dashkesan mine forms lustrous, pistachio-green fan-sprays of prismatic to acicular
crystals, and some of the Fersman specimens on hand at Denver are sturdy plates to 10 cm of such sprays tightly intergrown.
The structure of the heat treated specimens consisted of acicular
martensite and retained austenite foil a few tens of [micro]m thick
Structure of high speed steel R6M5 (EBCHR) after hardening consists of acicular
martensite, residual austenite, residues of carbide network over grain boundaries and structurally isolated carbides of compact form, uniformly distributed over the metallographic specimen section (Figure 1, c).
