Molecular structure, as imparted by processing, has a significant influence on the physical properties of extruded products. This is known as a process/structure/property relationship. In the case of blown film, the extruder conditions and the bubble geometry influence the molecular structure, which then affects film performance. 

Optimization of performance characteristics of textile products and processes is often the final stage in the engineering design where the results of experimental and theoretical modeUmg are combined in order to achieve the best possible combination of properties. In many cases this also includes consideration of economic and logistic aspects. It can be seen from the sections above that the process-structure-property system is governed by complex multi-factor relationships. In these conditions, the optimization problem can be formulated as a problem of finding a combination of independent factors X (optimal point) that provide an extremum... 

The development of high performance polymers, such as high modulus fibers and supertough polymer blends, has accelerated in recent years as a direct result of increased knowledge of process-structure-property relationships. Highly oriented... 

We present an example of these processing-structure-properties-performance principles in Figure 1.2, a photograph showing three thin disk specimens placed over some printed matter. It is obvious that the optical properties (i.e., the light transmittance) of each of the three materials are different the one on the left is transparent (i.e., virtually all of the...

With regard to the design, production, and utilization of materials, there are fom elements to consider—processing, structure, properties, and performance. The performance of a material depends on its properties, which in turn are a function of its structure(s) furthermore, structure(s) is (are) determined by how the material was processed. 

At this time, we have completed our processing/structure/properties/performance commentary for steels. By way of summary. Figure 11.29 shows relationships of these processing, structure, and property elements for this group of alloys. It was compiled from summaries provided in previous chapters and, in addition, includes topics discussed in this chapter. 

For the most part, the individual components found in the interrelationships of Figure 11.29 are conceptual in nature —that is, they represent the scientific (as opposed to engineering) aspects of materials. We have also generated a processing/structure/ properties/performance relational diagram (for steel alloys) taken from the materials engineering perspective it is shown in Figure 11.30.
