Strength of the components

In certain alloys and under certain environmental conditions, selective removal of one metal (the most electrochemically active) can occur that results in a weakening of the strength of the component. The most common example is dezincification of brass [164, 165]. The residual copper lacks mechanical strength. 

In certain alloys and under certain environmental conditions selective removal of one metal (the most electrochemically active) can occur resulting in either localised attack, with the consequent possibility of perforation (plug type), or in a more uniform attack (layer type) that results in a weakening of the strength of the component. Although the selective removal of metals such as Al, Fe, Co, Ni and Cr from their alloys is known, the most prevalent form of de-alloying is the selective removal of zinc from the brasses —a phenomenon that is known as dezincification. 

In mass spectrometers, ions are analysed according to the ml7. (mass-to-charge) value and not to the mass. While there are many possible combinations of technologies associated with a mass-spectrometry experiment, relatively few forms of mass analysis predominate. They include linear multipoles, such as the quadrupole mass filter, time-of-flight mass spectrometry, ion trapping forms of mass spectrometry, including the quadrupole ion trap and Fourier-transform ion-cyclotron resonance, and sector mass spectrometry. Hybrid instruments intend to combine the strengths of the component analysers. 

The strength of the component had degraded, hut this degradation had gone undetected and/or imcorrected. 

Control of crosslinking is critical for processing thermoset plastics, both the reaction prior to the gel point and that subsequent to the gel point. The period after the gel point is usually referred to as the curing period. Too slow or too rapid crosslinking can be detrimental to the properties of a desired product. Thus, in the production of a thermoset foamed product, the foam structure may collapse if gelation occurs too slowly. On the other hand, for reinforced and laminated products the bond strength of the components may be low if crosslinking occurs too quickly.

Solid oxide fuel cells (SOFCs) are composed of ceramic components and the mechanical reliability of these components is a significant issue in the development of SOFCs. In particular, the durability of the components against stresses during operation is a serious problem. To evaluate the mechanical reliability of SOFCs, the magnitude of the stresses in cell components and the strength of the components against the stresses must be considered precisely. Stresses in SOFCs are categorized into fom types.

There are a number of ways of calculating overall solvent strength in order to give isoeluotropic mixtures. One method is to express the strength as the product of the sum of the strengths of the component solvents with their volume fractions, i.e.

Lastly column 9 is reserved for comments and relevant information. This area gives the reviewer an opportunity to suggest improvements in design, methods to increase strength of the component (against the perceived stress) or perhaps needed user documentation considerations. 

P(l) The loads for the bonded joint analysis shall be obtained from the global analysis of the structure. The bonded Joint design ensures that the bondline is capable of transferring the applied loads between the Joint members and that the joints members (adherends) are capable of withstanding the Joint-induced internal loadings. The basic strength of the components to be Joined under the applied external loads shall be evaluated as a part of the component design process (Chapter 4). 

Surface reinforcements are applied to various mechanical components. One of the typical examples is shot peening for the automotive components made of steel. Giving the surface layer of the treated components large compressive residual stresses, shot peening improves fatigue strength of the components significantly. Therefore, surface reinforcements play important roles to the metallic mechanical components. However, no useful surface treatments have been developed for the structural ceramics yet. 

Polypropylene is intrinsically less resistant to ultraviolet radiation. Although polypropylene shows powdering rather than grass surface grazing after sunlight exposure, minute surface cracks are visible under the microscope. Under certain conditions the microcracks can act as points of stress concentration. This can reduce the impact strength of the component. 

The greater the differences between the components of the mixture to be separated, the greater must be the range of solvent strength of the components of the eluent.

The term quality is relative and depends on the particular application. While in one case it is already sufficient to ensure a complete filling of the molded part, the specifications are in other cases far beyond the objective. The location of weld lines, the strength of the components, the quality of the molded part surface, and even the dimensional accuracy and reproducibility are criteria, which affect the term quality significantly throughout production.
