What is the Difference Between FCC and HCP? (Crystal Structure . . . FCC and HCP are both close-packed with a 74% atomic packing factor, 12 nearest neighbors, and the same interstitial sites However, HCP only has 3 slip systems, while FCC has 12 slip systems, which lead to very different mechanical properties
Close Packed Structures: fcc and hcp | Physics in a Nutshell How close-packed structures of spheres can be constructed: In a first layer the spheres are arranged in a hexagonal pattern, each sphere being surrounded by six others (A) Then a second layer with the same structure is added
Close-packing of equal spheres - Wikipedia They are called face-centered cubic (FCC) (also called cubic close packed) and hexagonal close-packed (HCP), based on their symmetry Both are based upon sheets of spheres arranged at the vertices of a triangular tiling; they differ in how the sheets are stacked upon one another
Orientation-dependent lattice rotation and phase transformation in an . . . The cube-oriented grains with their 〈001〉 directions close to the loading direction undergo face-centered cubic (FCC)-to-hexagonal close-packed (HCP) phase transformation due to the activation of octahedral slip involving multiple slip systems
What is the difference between FCC, BCC, and HCP structures? Key Differences Between FCC, BCC, and HCP Atomic arrangement: FCC has atoms at cube corners and face centers, BCC at corners and the center, while HCP is hexagonal-layered Ductility: FCC has the highest ductility, BCC moderate, and HCP lowest Strength: BCC and HCP generally have higher strength than FCC
The mechanisms of γ (fcc) → ε (hcp) → α′ (bcc) and direct γ (fcc) → α . . . Here, we reported the strain-dependent direct transformation of γ (fcc) → α′ (bcc) in addition to the γ (fcc) → ε (hcp) → α′ (bcc) sequence in a gradient austenitic 304 stainless steel And we proposed the new mechanisms involved in the two transformation sequences
FCC vs. HCP — What’s the Difference? FCC (Face-Centered Cubic) structures pack atoms densely, maximizing space efficiency, while HCP (Hexagonal Close-Packed) structures offer unique directional properties
Comparison of SC, BCC, FCC, and HCP Crystal Structures Here are the links for the thorough comparisons of: FCC vs BCC, and FCC vs HCP Here are the crystal geometric ratios for simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed
