Over the years, our capabilities have expanded to include deep drawing, stamping, hydroforming, cnc spinning, beading and trimming. Sketch the {110} and {112} slip planes in bcc structure. Both compositions were annealed at 700°c. Cold worked structures normally exhibit deformed grain structures with considerable slip (bcc and fcc metals) or mechanical twinning (hcp metals).

Bcc metals are less ductile but stronger, eg iron, while hcp metals are usually brittle. Examples of hcp metals include zinc, titanium, and cobalt. Like the fcc structure, the hcp structure is based A = b ≠ c o α = β = 90o , γ = 120 atomic positions: In hcp metals, mechanical twinning therefore goes along with dislocation.
