WebJul 27, 2024 · The Bi 3 In 5 phase is generated in a peritectic reaction (liquid + biIn → Bi 3 In 5) at 88.9 °C and forms a eutectic with BiIn 2 at approximately 64.6 mass% In and 88.7 °C. The ɛ-phase is also generated in a peritectic reaction (liquid + (In) → ε) between 93.5 and 49 °C, and forms a eutectic with BiIn 2 at 78.5 mass% In and 72.7 °C. WebAbstract The mechanism and kinetics of the peritectic phase transition in steel were studied by using a concentric solidification technique in a high-temperature laser-scanning confocal microscope. Strong solute diffusion fields are established during solidification of the primary delta phase, which leads to suppression of nucleation of the austenite phase, and hence … boba heart milktea shop https://pixelmotionuk.com
