]. Fig. 6 HRTEM image (a) and FFT (b) showing fcc phase and bcc phase particles of Ti-13Ta-9Sn alloy and selected FFT (c) and inverse FFT (d) of magnified zone (white square) in (a) Fig. 7 Gibbs free... a faster diffusion process, leading to the amorphous phase formation [49]. The main requirement for the formation of an amorphous phase is that large difference in atomic radius among the constituent......

evolution during solidification. Key words: Al-Cu-Mg alloy; hot tearing; solidification; eutectic reaction; low-melting-point (LMP) eutectics; thermodynamics 1 Introduction Hot tearing has been one... [4,5]. The subject with respect to effects of intermetallic phase formation and eutectic reaction during solidification on the fluidity and feeding ability of residual liquid in ferrous and Al alloys......
concentration is dense. And in the time zone observed by the naked eye, the froth image changes and the size distribution of the froth are almost consistent in a short time. The probability of individual......
in the micro zone through SEM and EDS analysis. Figure 4 shows SEM images of a granite sample at magnifications of 200 times, 500 times and 2000 times. The secondary electron image (SEI) clearly shows......

of Inconel 718 superalloy in the temperature range of 950-1150 °C and strain rate range of 0.001-100 s-1. The results showed that the distribution of dynamic recrystallization zone in stable region..., Co atoms can substitute Ni atoms during material preparation, leading to a reduction of atomic order degree, so the diffusion activation energy of the alloy would be increased [27]. Since the self......
