why are FCC metals more ducticle than BCC metals?

there are a greater number of close packed planes that can operate as glide planes for dislocations

Silver has a higher reflective index than any other industry-related metal anhydride.  For economic purposes, titanium isn't used in most commercial labs.  However in some superconductors, the 0.003% difference is crucial.  Though it costs much more.

You need to look at a Periodic Table. The farther to the left of the table an element is, the more metallic it is.

Cable is drawn, not molded. A piece of material is drawn through a set a wheels, or dies. Drawing the material through the dies results in a narrower but longer piece of material. The proces is repeated through ever smaller dies until the cable has reached the desired diameter.

Nickel is harder than copper and provides better penetration into the target. Copper is softer and tends to mushroom much faster once it enters its target. \nIf you want penetration go for the nickel\nIf you want displacement go for the copper

A crystal shape is the arrangement of the molecules in a compound...carbon fiber is a crystalline structure since it is arranged in a pattern when observed under a microscope. Glass, however isn't a crystalline structure, and will be disorganized. Also, a quick fact is that glass will always be in motion due to it's non-crystalline structure. The bottom of a pane of glass will be thicker than the top after many years :) A high melting point means that it will take more heat to induce a state change... Metal is frozen at room temperature and has a high melting point, as opposed to water, which has a melting point around 33 degrees farenheit.

The coefficient of expansion is greater for metal than for glass.

2-all of the microstructure of it is a structure named Perlit(consists of ferit and cemantite , later is a hard phase) . all of matterial that is very hard they are brittle unless we treat them.3- all of cast iron is not britle we hane ductile cast iron but generally they are britle because of cemantite phase.4- it is very hard then is brittle.5- because when tempering harsness decreases.6- it deponds on final application.1-all of alloys that are weak they are ductile . we need smaller force to reform them.hope they are useful for you.

Tungsten has at least three times the melting point of copper, and they are both conductors, but when it comes to electricity, Copper is the winner, because Tungsten has more resistance to electricity therefore it is less conductive than Copper.\n\nTungsten due to its resistance is used in Light bulbs,\nand copper, which is more malleble  is used in mostly covering wires.\n\nHope it helps,

It leads to anisotropy, the quality of exhibiting properties with different values when measured along axes in different directions.\nForging refines the grain structure and improves physical properties of the metal. With proper design, the grain flow can be oriented in the direction of principal stresses encountered in actual use. Grain flow is the direction of the pattern that the crystals take during plastic deformation. Physical properties (such as strength, ductility and toughness) are much better in a forging than in the base metal, which has, crystals randomly oriented.

Certin metals which are much more electropositive than hydrogen(viz. metal which are placed above hydrogen in the electro-chemical series) react with many acids and liberate hydrogen gas.in those cases ,the displcement of hydrogen of the acids takes plce diretly.but in majority of cases,this displacement process offurs through reaction between the acids and the oxides or hydroxides of metals.\nAcids also charatrised by their tendency to react with metal carbonates and bicarbonates evolving carbon dioxide.

it depends on the material, you could have FCC, BCC, HCP and many other crystal structures, with many different substances present dependent on the alloy

boundaries between crystal grains are less well defined than the actual crystals, and have a different refractory index or optical density.\n\nIn anisotropic crystals, the refractory index or the surface structure of a transparent cut also depends on the orientation of the crystal.

Do you see any high performance airplanes  or centrifuge rotors made of plastic instead of titanium?  I think you just answered your question. . .\n\nThat is a little glib, because tensile strength is only one mechnaical property (specific strength, hardness, etc). Stiffness is another reason titantium is popular.  Pure titanium has tensile strengths from 250 to 750 MPa. Ti alloys go up to 1250 MPa. \n\nIf you really only care about tensile strength in **one direction** then there are materials. Heat treatment of carbon fibers can generate tensile strengths as high as 5650 MPa.  Such fibers can be part of a plastic composite and nearly all of them will be less dense than titanium. Molecular weight is ill defined in such compounds and probably not what you meant.

The grain structure continually refines itself as the piece undergoes stress and strain. This is known as "work hardening". The ductility lessens, and the piece becomes more brittle.

High tensile strength steel...however there are other non-metals that are actually stronger...carbon fiber materials being one possibility.
