The extreme case of the microstructure gradient is a formation of the peripheral coarse grain structure (PCG).
These experiments included different alloy chemistry, various temperatures, extrusion ratios and extrusion speeds allowing analysis of their influence.
The material used was 6061 aluminum alloy with a chemistry within the Aluminum Association's standards for this alloy.
In order to understand the effect of chemistry on recrystallization response, two alloys representing Cr:Mn ratios of 1:1 (Low Cr) and 2:1 (High Cr) were used.
Two billet temperatures, extrusion ratios, ram speeds, and alloy chemistries were utilized to investigate the effect of process parameters on PCG depth.

The ZSM-5/MCM-41 zeolite with a core-shell structure exhibited a higher conversion of supercritical n-dodecane cracking compared to ZSM-5.
Summary The core-shell-structured ZSM-5/MCM-41 composite materials were synthesized by desilication and re-assem -bly processes.

By FTIR analysis it was known that because of the force-chemistry of polymer and time-temperature equivalence principle, resin chemically reacted with rubber during the mixing process. 1.
This kind of structure made the blending system have good toughening action, so the friction material had better performances.
This analysis was consistent with the conclusion in above paragraphs, thus the macroscopic performance of friction material was explained from microcosmic structure.

Because of the force-chemistry of polymer and time-temperature equivalence principle, resin chemically reactes with rubber during the mixing process.

Physical and chemistry properties were chosen as comparison sequence, expressed as Xi={Xi(k), k=1,2,…,m, i=1,2,…,n}
Specific surface area and structure damage ratio have least influence to soil.
Specific surface area and structure damage ratio have least influence to soil.
The structure damage ratio of soil represents the condition of structure damaged under the action of flow impact, it has intimate connection to dispersivity.
(2) Comparing each physical chemistry properties comprehensively, the most principal influence to dispersion degree were CEC and ESP, the correlation degree of them were lager than 0.7.

In addition to refine the microstructure, both the thermomechanical treatments and chemistry variations may also alter the shape and distribution of the strengthening phases.
The change of the chemistry is another important approach in changing the microstructure because it can change either the eutectoid point or eutectoid temperature.
The lamellar structured composites are composed of two phases, as shown in Fig. 1.
Among all those components, both the copper and silver have the fcc structure, a ferrite has the bcc structure, and the cementite has the tetragonal structure.

The determination of detailed structure of copolymers has advanced considerably over recent years with the advent of pulsed 13 C RMN spectrometers [13-15] .
For the CHMA-TtEGDMA copoly-mers r1 > 1 and r2 < 1, meaning that the rate of TtEGDMA incorporation into the copolymer structure is much higher than the rate of CHMA incorporation.
The structure of copolymers was confirmed by 13C NMR spectroscopy.
