• Atoms may assele into crystalline or amorphous structures. • We can predict the density of a material, provided we know the atomic weight, atomic radius, and crystal geometry (e.g., FCC, BCC, HCP). • Material properties generally vary with single crystal
Figure 2-2 shows a schematic microstructure of DP steel, which contains ferrite plus islands of martensite. The soft ferrite phase is generally continuous, giving these steels excellent ductility. When these steels deform, strain is concentrated in the lower-strength ferrite phase surrounding the islands of martensite, creating the unique high initial work-hardening rate (n-value) exhibited by

Aluminum fencing typically costs anywhere between $25 and $40 a foot, whereas fences made from other materials, like wrought iron or steel, can cost upwards of $50 a foot. In addition to the higher upfront cost of wrought iron and steel fences, these types of fences require extra maintenance because they are not weather resistant like aluminum.

Steel in most cases performs far better in earthquake than most other materials because of these properties. However one important property of steel is that it quickly loses its strength in a fire. At 500 degrees celsius (930 degrees F), mild steel can lose almost half its strength.

United Aluminum can supply these alloys, sometimes referred to in the group of “Aerospace Alloys” for their practical appliions in the aviation industry. Aluminum has many benefits over other materials, including a high strength to weight ratio, corrosion resistance, formability, and price.

Light gauge steel construction is very similar to wood framed construction in principle - the wooden framing meers are replaced with thin steel sections. The steel sections used here are called cold formed sections, meaning that the sections are formed, or given shape at room temperature.
Dry corrosion or oxidation occurs when oxygen in the air reacts with metal without the presence of a liquid.Typically, dry corrosion is not as detrimental as wet corrosion, but it is very sensitive to temperature. If you hold a piece of clean iron in a flame, you will soon
10 Advantages of concrete Advantages of concrete. Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials. 10 major advantages of concrete are explained below.1. Concrete is
STEEL --- HARDENABILITY 23. Heat treatable steels generally have high hardenabilities. Comparing a 1040 steel with a 4340 steel, how much deeper can the 4340 steel be hardened to level of Rc of 50? (A) 60mm (B) 45mm (C) 30mm (D) 15mm

Three common steel structures found inside a substation. Before electricity can travel into your home, it must pass through a substation first. A substation is an asselage of equipment where electrical energy is passed in order to be stepped up or stepped down.

Primary Metallic Crystalline Structures (BCC, FCC, HCP) As pointed out on the previous page, there are 14 different types of crystal unit cell structures or lattices are found in nature. However most metals and many other solids have unit cell structures described
Because cold-formed steel (CFS) framing is light weight, extremely strong, noncoustible, and relatively easy to install, it has dominated the market for interior, non-loadbearing partition walls in commercial construction. Now, with advanced technological
