摘要:
利用快速凝固单辊平面流铸技术,通过调整各种工艺参数,成功地制备了Ni20Zr 10 Al70非晶合金条带.利用XRD、TEM和SAED等手段对合金的非晶态结构进行了验证,并对不同凝固速率下合金的相组成进行了分析.结果表明:随着凝固速率的提高,Ni20Zr 10Al70合金的凝固首先是NiAl3相与α-Al相的结晶受到抑制;随着凝固速率进一步增大,Ni0.3 Al1.7Zr相的结晶也受到抑制;凝固速率再进一步增大,Ni2Al3相的结晶也受到抑制,最终得到完全的非晶态结构.
Abstract:
Ni20Zr 10 Al70 amorphous alloy strip was successfully prepared by adjusting various process parameters by using rapid solidification single-roll planar flow casting technology. The amorphous structure of the alloy was verified by XRD, TEM and SAED, and the phase composition of the alloy at different solidification rates was analyzed. The results show that with the increase of solidification rate, the solidification of Ni20Zr 10Al70 alloy is first inhibited by the crystallization of NiAl3 phase and α-Al phase. With the further increase of solidification rate, the crystallization of Ni0.3 Al1.7Zr phase was also inhibited. The solidification rate is further increased, and the crystallization of Ni2Al3 phase is also inhibited, and finally a complete amorphous structure is obtained.
