图4 Y4.5样品不同温度下以0.33 K/s的升温速率加热时有自放热过程、无自放热过程和以1.67 K/s的升温速率快速加热过程的结构因子S(Q)和约化对分布函数G(r) (a, d) plots for the sample with a self-heating process with heating rate 0.33 K/s (b, e) plots for the sample without self-heating during a normal slow heating process with heating rate 0.33 K/s (c, f) plots for the sample with a fast-heating rate (1.67 K/s)

Fig.4 S(Q) (a-c) and G(r) (d-f) plots of Y4.5 MGs under different temperatures (The G(r) plots illustrate that the crystalline products for the samples after heating with different rates are different. S(Q)is the structure factor, G(r)is the reduced pair-distribution function, Q is the scattering wave vector and r is the distance in real space)
