complexation, electron-transfer reactions, solubility and precipitation equilibria, microbial transformations, and diffusivity (Bodek et al., 1988). The following sections address the application of hard and soft acid and base (HSAB) concepts to metal behavior, including the formation of metal complexes, and the importance of Influence of cooling rate on secondary phase precipitation Apr 09, 2016 · During continuous casting process of low carbon micro-alloyed steel containing vanadium, the evolution of strand surface microstructure and the precipitation of secondary phase particles (mainly V(C, N)) are significantly influenced by cooling rate. In this paper, influence of cooling rate on the precipitation behavior of proeutectoid -ferrite at the -austenite grain boundary and in the

Investigation of precipitation behavior and related

Jan 25, 2009 · The precipitation behavior and related hardening in AA 7055 aluminum alloy aged at 120 and 160. °C was investigated in detail.. GPI zones were the dominant phase in the alloy upon ageing at 120 °C for 60 min.The metastable phase begins to precipitate in the alloy after being aged at 120 °C for 60 min, and turns to be the main phase after ageing for 300 min. Precipitation of Secondary Phase and Phase Transformation Also, the phase transformation behaviors and precipitation features of secondary phase of a solution-treated TC4 alloy during high-temperature aging were studied. [43] Ahmed et al. [44] DOI:10 Unveiling precipitation behavior in Mg-Y based alloys Apr 01, 2021 · Our work reveals an undiscovered precipitation behavior that a novel t phase is identified to exhibit an in-situ transformation from phase. The precipitation sequence of Mg-Y based alloys is thus identified as SSSS clusters/G.P. Zones (Mg 7 Y) / t (Mg 3 Y). Our finding provides a guideline for

Precipitation and transformation of phase in a selective

The transformation of phase is owing to Mo diffusing during the aging processing. The nucleation points of -Cr phase are mainly located at triple junction, incoherent / interfaces, subgrain boundaries and other high energy interfacial regions. The unique precipitation behavior leads to the small size and uniform distribution of the
