摘要:
用X射线精细结构分析、示差扫描热分析和扫描电子显微分析仪分析研究了FeNiPB(Cu,Nb)合金的非晶及晶化的微观组织结构,探索了这类合金的非晶加纳米晶组织结构的形成和控制,结果表明:Fe,Ni,P,B,Cu和Nb元素混合粉末机械合金化后可形成非晶态的FeNiPB(Cu,Nb)合金,再经过晶化处理可得到具有非晶基体上弥散分布着α-Fe基纳米晶组织的合金.在晶化过程中,合金中Cu的作用使α-Fe晶核弥散形成,而合金中Nb的存在阻止了α-Fe基的晶粒的长大.因此,在FeNiPB(Cu,Nb)合金中,可通过调整合金中Cu,Nb的含量及相对量来控制非晶基体上的纳米晶形成的量及晶粒尺寸.
Abstract:
The microstructure of amorphous and nanocrystallite in FeNiPB(Cu,Nb)alloy were analyzed and studied by extended X-ray absorption fine structure analysis, differential scanning calorimetry and scanning electron microscope. The mechanism of the formation of the microstructure of amorphous and nanocrystallite in FeNiPB(Cu,Nb)alloy were researched. The results show that the FeNiPB(Cu,Nb)amorphous alloy can be formed by ball milling the mixed powder of Fe, Ni, P, B, Cu and Nb. After heat treating dispersive nanocrystallites separate out from the amorphous matrix. In crystallization the role of Cu is to promote the nucleation of α-Fe and the existence of Nb can obstruct the growth of α-Fe crystallites. Therefore the amount and size of the nanocrystallites in FeNiPB(Cu,Nb)alloy can be controlled by adjusting the amount of Cu, Nb.
