试验用不同预处理温度对Fe67.5Ni1Al5Ga2P9.65C6.75B4.6Si3Sn0.5试样在晶化处理之前进行热处理,并利用XRD、DSC等对其进行结构和热力学分析。通过分析发现,在较低温度的预退火处理之后,合金内部原子间相互扩散,异种原子之间的原子相互结合,形成原子团簇或是原子集团。经过预处理的非晶试样进行部分晶化后,其晶粒尺寸减小,析出相的分布也更均匀,晶化处理之后的晶化面积较大,晶化相的种类更多,非晶合金的内部结构和状态发生了改变。在一定范围内,随着预退火温度的提高,非晶合金的晶化面积也随着增加,晶体的生长速度更快。
The experiment pre-treated Fe67.5Ni1Al5Ga2P9.65C6.75B4.6Si3Sn0.5 samples with different pretreatment temperature before heat treatment, and the use of XRD, DSC and other structural and thermodynamic analysis. It is found through analysis that after the pre-annealing at a lower temperature, the atoms in the alloy diffuse into each other, and the atoms in different kinds of atoms combine with each other to form atomic clusters or atomic groups. After the pretreatment of the amorphous sample partially crystallized, the grain size decreases, the distribution of the precipitated phase is also more uniform, the crystallization area is larger after the crystallization treatment, and the type of the crystallization phase is more amorphous. The internal structure and state of the alloy have changed. Within a certain range, as the pre-annealing temperature increases, the crystallization area of the amorphous alloy also increases, and the crystal grows faster.
