Strengthening of Mechanics of Metals
1. IntroductionThe commercial metal products are made primarily of tremendous number of single grains or crystal that do not deform according to the simple laws. The preparation and purity of the initial dislocation of substructure and density can be generally predicted in the high precision of the function, temperature, strain, as well as the stress rate. Nevertheless, the use of the still greater complexity can be use in order to produce materials that has the highest usefulness and strengths. The various mechanism in the strengthening the mechanisms as well as the other aspects for the deformation can be considered (2008).
2. Common Ways of Metal Strengthening
There are many ways in strengthening the mechanics of metals. One of these is the strengthening form the grain boundaries. This means that the simple grain boundary can have to inherent the strengths due to the results of the grain boundaries from the interference of the slip grains which are mutual. The other way is the strain aging or the type of way which is commonly correlated to the phenomenon of yield-point whereas the strengths of the metal can increase while the ductility can be lessen through the heating of the temperature right after the cold-working. The solid solution strengthening can also be way in order to strengthen the metals and can produce alloys which are stronger as compare to the pure metal (Ibid). One of the ways also is the strengthening from the fine particles which are the hard particles that are mixed in the consolidated and matrix powder fro metallurgy technique while many of the alloy systems can strengthened with the aide of the precipitation reaction in the solid states. From the Modulus Change, it can also be source of strengths and the variation of the elastic module as the matrix and precipitate will be the ways for strengths ( 2008).
3. Strengthening Aluminum
The age hardening or the precipitation hardening is the technique that most of the experts are using in order to strengthen the malleable materials that includes the structural alloy of aluminum. This relies on the changes of the solubility of solid with the given temperature that can produce the particles of the phase of impurity that can impede the dislocation movement and can lattice the crystals because the dislocations can serve as the carrier of dominance of plasticity and can harden the material. The solid solution and precipitation for the atoms in the lattice can increase the resistance of the slip which is strengthening mechanisms. This interaction of precipitates and disclosure can produce either softening or hardening. This interaction of disclosure with the solid solution atom, to the precipitate, in the cells, grains cells, and to the sub grains can be isotropic effects of hardening which can be presented through the scalar drag stress or hardening. The initial strengths of the aluminum can increase the particle size and to reach the peak levels to the maximum hardness. This had been founded by that observed the hardness of the Al- 4% in an increase time to the ambient temperature right after it has been quenched to the high temperature ( 2006,).
This precipitation is applicable in aluminum in order to add strength in it. In this method it can maintains the ageing times for up to 1000 h and the treatments of tempering to 650o C which will be needed by aluminum. It can be achieved through the solute atoms in the dissolved so that it can form the solution of single phase and the supersaturated solid solution in the remaining stable and heat the treatment to induce the precipitation to keep some of the time aging and cannot find to the other strengthening techniques.
4. Metal Strengthening affects Skateboards
Accordingly, strengthening is the ability of a metal to deform or distort depending on the ability of dislocations to move. Restricting the dislocation motion of metal makes it stronger. It is said that strengthening reduces ductility of the materials, which is important for manufacturers. Strengthening changes the way the carbon atoms in the steel affects the hardness of the material.
Metal strengthening is said to have effects on skateboards. There many types of skateboards and some of them have these adjustable features to suit board flexibility and for accommodating performance requirements of different maneuvers executed by skateboarders. A skateboard with hardened or strong can secure the underside of an arched end of the skateboard. Hardened or strengthened metal plate for skateboards can provide a ribbed-skidding performance. Strengthening metal mechanism can also provide mechanical strength for the skateboarder.
The strengthening of metals for skateboards also relates particularly to the enhancements in skateboards as well as the like, specifically to new and enhanced skateboard in which a protective shoe or plate. In the skateboard zone, it has been a major practice to use metal to provide durable and strong assembly. Although these materials have served their purpose, metals should still be hardened or strengthened to prove their importance in the skateboard.
The metals in skateboards can be found at the wheels which bear the weight the person and the skateboard integrated but also give or maximize immovability. Although there are no particular standards or criteria for skateboard metals or bearings, it can be said that experts try to strengthen the metal to give them smooth rite and enhance their performance while riding with it ( 2008). Skateboards can be made of woods, plastic and metals, but most prefer to use metals in order to enhance their presentations and routines. In addition, it also helps them to make additional exhibitions when they are performing or doing the sport.
All in all, it can be said that metal hardening or strengthening is important to secure the capabilities and the performance of skateboards. It helps skateboarders to run smoothly to give their best performance. In addition, strengthened metals secure that all parts is well-balanced. In choosing materials for skateboards, it is essential that one should choose materials that can be strengthened to ensure long-lasting durability and flexibility. Furthermore, skateboarders should often check their skateboards to know which parts to needs to be fixed and hardened.
