WebHexagonal close-packed (HCP) metals and alloys, which include titanium, zirconium, magnesium, etc., are extensively used in a variety of industrial sectors. For example, … WebAlpha-iron and tungsten have the bcc form. The fcc lattice is both cubic and closely packed and forms more ductile materials. Gamma-iron, silver, gold, and lead have fcc structures. Finally, HCP lattices are closely packed, but not cubic. HCP metals like cobalt and zinc are not as ductile as the fcc metals.

WebJul 22, 2015 · Hcp just has fewer than the higher-symmetry fcc, and for a given grain may not be optimally oriented to slip. Bcc doesn't have any close packed planes, and the dislocations that might lead to slip often decompose into partials lying on different planes, so their movement is very difficult without thermal activation to reconfigure onto one slip ... kfvs12 news heartlandWebCredit: Callister & Rethwisch 5e.
