 revealed that the strong (111) preferred orientations with fine columnar structure
and little Cu content are essential to achieve better hardness in Zr-Cu-N nanocomposite coating system.
The cracking was even more severe in the case of the Ti[B.sub.2] (1.2 [micro]m thick, dense columnar structure
, P6/mmm cell with lattice parameters of 3.009 [Angstrom], 3.009 [Angstrom], and 4.276 [Angstrom], grain size of ~33 nm, and effective elastic modulus of 430 GPa) with the hardness of 30 GPa shown in Figure 1(c).
SEM cross section of all coatings showed a columnar structure
as shown in Fig.
The coatings have a columnar structure
, which is similar with previous studies.
In the Cu-1.7% Fe condensates, a large proportion of the crystals have the columnar structure
with fully fragmented twins, oriented in the direction normal to their growth <111>(Figure 2b).
The columnar structure
may be due to the direction of the stream of plasma from the target nonperpendicular to the substrate .
1 is different from the columnar structure
of acrotretoid brachiopod shells (Williams & Holmer 1992), as well as from that of Mickwitzia shells (Skovsted & Holmer 2003), where columns penetrate initially organic-rich layers.
Both prismatic and columnar structure
types refer to aggregates that are taller than they are wide.
Using the Welsh system must take the columnar structure
of such basis importance, even easier to understand.
The vein filling has a massive to roughly columnar structure
, and when cavities are present, a few crystal forms are developed.
If this is seen as a model, both the monumental columnar structure
and the rotunda immediately yield much deeper resonances.
