Relative hardness profiles

Figure 3 shows profiles indicating changes in relative hardness on cross-sectioned samples of the EPR material of Fig. 1. For unirra-dlated material, the profile is essentially flat (x s). For the samples Irradiated at 6.7 x 10- rad/h, a distinct flat-bottomed, U-shaped profile is seen (circles). The boundary position between optical bands (photo B, Figure 1) corresponds to the steep part of...

Another important aspect of FSP-assisted thick-section bending is the influence of the heat generated during FSP on subsequent parent-metal properties. With large aluminum blocks and the relatively low travel speed coupled with the conservative overlap per pass, considerable heat buildup occurs. The hardness profile for the processed 7050-T7451 plate is shown in Fig. 14.18 as a function of depth below the surface, and the microstructure is shown in Fig. 14.19,... 

The reason for this differing reactor behaviour becomes understandable if the relative concentration profiles of the added component, which are also shown in this figure, are discussed. Cases a and b are characterized by the fact that hardly any accumulation of this component occurs during the first half of the feed phase. In simple terms this means that each amount added to the reactor is converted spontaneously. Only towards the end of the feed time the added component accumulates slightly, reaching its maximum relative concentration at the stoichiometric point.

The behavior of assoeiating fluid near the hard wall was extensively studied in the framework of the theory diseussed above. The model of Cummings and Stell was applied to relatively dense fluids at a high degree of dimerization [33,36]. Fig. 1 presents the density profiles ealeulated within the framework of the eombined PYl/EMSA theory (i.e., the density profiles were evaluated from the PY 1 equation, whereas the bulk direet eorrelation fune-tions follow from the EMSA equation) and HNCl/EMSA approximations [33]. The ealeulations were performed for L = 0.42[Pg.181]

Trace metals are resolubilized from the biogenic hard and soft parts in much the same way as the macronutrients. Thus, the depth profiles of the trace metals with high EFs tend to be similar in shape to those of the nutrients. Efforts have been made to develop a Redfield-Richards type ratio far the trace metals in marine plankton. Surprisingly, field and lab work suggests that a relatively constant composition can be defined for whole... 

Below is an example of pilot work in support of a scale-up to production. In this example, the final blend was compressed on a 16 station rotary Beta press using ovaloid tooling. A compression profile, as shown in Figure 9, was generated. The speed of the tablet press was fixed at 78 rpm. Forces ranging from 8 to 28 kN were evaluated. Lamination was observed at forces greater than 25 kN. The curve was relatively flat between 15 and 25 kN forces with hardness ranging from 175 to 215 N.
