In a similar manner to specimen 1, the forged product is undergone a full annealing P2 at a temperature of 530° C approx for 3 hours. Such full annealing can improve the mechanical process ability of the

It has an excellent strength to weight ratio obtained from heat-treatment used in its formation. The heat treatment used for this steel does not use quenching rather uses air cooling or air

Overall, the 1018 and 1045 steel specimens displayed similar relationships between the heat-treating procedures. The 1045 steel had a greater tensile strength in all states except for the quenched state. In general, the 1018 steel specimens were more ductile than the 1045 steel specimens in all states.

After the explosion, the metal is often highly deformed has to be heated to soften it or through a series of rollers depending on the metal

Shape memory alloys (SMA) have attracted much attention in recent years, since they are smart (or intelligent) materials, as well as functional materials, which already exist. These alloys possess the characteristics of the shape memory effect (SME) and super-elasticity (SE) which are caused by the martensitic (or displacive) transformation (MT) and its reverse transformation to the parent austenite phase; we define the characteristic transformation temperatures as follows;

The great thing about this knife is that it can be used for so many purposes. You are not confined to one use for this knife. It can be used if you're going hiking, camping, hunting--any outdoor activity really. You can keep it in your backpack or keep it on your person to have handy.

Sample 1 demonstrated characteristics of a medium carbon steel. It softened during the annealing process and progressively hardened with each increase in quench rate.

The steel industry is something that has been evolving and changing for the past 3 centuries in which the braced metal has been around. As we come into the modern age of mining and metal production we can find that there have been difficulties in the way of our resources are beginning to run low, mining is dangerous, we may not have enough fuel to smelt iron in the next century, and abrasive water cutters are not innovating since their introduction. In the recent wake of these events an unlikely source has been uncovered to help aid these problems and that source is the math and physics of pokemon. Pokemon is a franchise of turn based RPG games in which creatures with many crazy features fight each other for glory. Over the years pokemon has been getting crazy with what these creatures are based on and some designs and descriptions hold the key to remedying these problems with the metal industry. Currently, the metal industry, while strong, has many problems due to the shrinking of natural resources and lack of innovation. the mathematics of pokemon could lead a revolution in steel production because Excadrill design could lead to a more efficient drill, the heat given off by magmortar is enough to create a new smelting and improve process for stronger steel, and the amount of pressure that Blastoise's cannons would be forcing out can make a already good tool even better.

Aluminium (AL) alloy 6061 is one of the most extensively used of the 6000 series aluminium alloys. Among the various useful aluminium alloys, aluminium alloy 6061 is typically characterized by properties such as fluidity, cast ability, corrosion resistance and high strength-weight ratio. Aluminium-based alloy MMCs has received increasing attention in recent decades as engineering applications. This alloy has been commonly used as a base metal for MMCs reinforced with a variety of fibres, particles and whiskers. Tungsten carbide (WC) is approximately two times stiffer than steel, with a Young's modulus of approximately 550GPa, and is much denser than steel or titanium.

This experiment demonstrated some key differences in material properties of several heat treatments for 4140 steel. Annealing creates a soft and ductile material that is easy to machine and perform other operations on. Quenching creates a very hard and brittle material that has extremely high yield and tensile strengths. Tempering quenched steel softens the steel and provides a tradeoff between the hard and strong quenched steel and the soft annealed steel. Engineers are benefited by an understanding of heat treatment because they are better able to predict how a material will perform when loaded if they know the heat treatment state of that material. Thus the results of this experiment, and others like it available in literature, are very

The process of pouring molten metal into a mold is what they do to make swords at factories, but where made through forging the metal in to a blade. In this paper that you are about to read it will be talking about the real way that swords are made. Such as the many types, the process of it itself, and the materials they used

The use of steel rebars was started in construction in 18th century. Cast iron was used in the earlier age. Cast iron rebars were of high quality, and there was no corrosion. The technique was refined by embedding the steel bars in concrete. Square twisted steel bars (deformed bars) were introduced in 1960s but these were phased out due to their inherent inadequacies. Later the steel rebars of high yield strength were produced by raising carbon (>0.5 and <1.0 wt% content) as well as manganese contents. Carbon was added to steels in order to achieve strength and later on it was realized that higher content of carbon created problem of brittleness and accelerated rate of corrosion (due to the presence of higher proportion of cementite phases

Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.

The Tensile tests were carried out on the fabricated welds according to the standard given by the ASTM E8M- 04, the welded plates are marked for the right dimensions and sheared manually to a width of 100mm. Generally two tensile pieces are cut from each welded joints piece for accuracy. The specimens are noticeable for identification, the centre of the weld is identified and 40 mm mark is made to facilitate the measurement of elongation after the test sample breaks under tension the specimens at the marking
