Implications of Microstructure in Helium-Implanted Nanocrystalline Metals
WebJul 21, 2016 · The conclusions are: 1. According to grain size, uniform elongation of single-phase FCC/BCC metals can be divided into low elongation (< ~1 μm), nearly constant elongation (~1 to ~200 μm), and decreased elongation with large scatters stage (> ~200 μm). In low elongation stage, uniform elongation increases rapidly and abruptly in a … WebOct 9, 2015 · For example, Cu-Al-Mn shape memory alloys that undergo a β 1 (bcc) ↔ β 1 ʹ (monoclinic) martensitic transformation exhibit superelasticity. Their recoverable strain is significantly improved when microstructural parameters, such as crystallographic orientation, grain size, and constituent phases, are optimized [1,2]. devil\\u0027s eye brewing
Observations of grain-boundary phase …
WebMar 18, 2024 · The theory of grain boundary (the interface between crystallites, GB) structure has a long history 1 and the concept of GBs undergoing phase transformations was proposed 50 years ago 2, 3. The ... WebWe use atomistic simulations to investigate grain boundary (GB) phase transitions in elemental body-centered cubic (bcc) metal tungsten. Motivated by recent modeling … WebFeb 1, 1995 · In grain boundaries with a high segregation level the nature and content of the major element strongly vary with GB crystallographic parameters, depending on the orientation of the grain boundary plane. HREM studies of grain boundary structure do not reveal any intergranular glassy phase in the material. References (39) P.H. Pumphrey churchill alabando hitler
