摘要
用碳离子注入到金属Fe和Ni中形成六方相。在Co中第一次形成了六方碳化物,晶格常数为a=0.268nm,c=0.433nm。同常规热处理方法比较,离子注入更倾向于形成简单晶体结构相、非晶相,而不容易形成复杂结构相。这一规律可以指导一般的离了注入实验并预期其他新相的形成。
A new phase, i, e. hexagonal cobalt carbide with α=0.268nm and c = 0.433nm was formed by carbon ion implantation. The only phase formed for the three ferromagnetic metals, i. e. bcc. Fe, hcp. Co and fcc. Ni after carbon ion implantation was the corresponding hexagonal carbide respectively. Structural simplicity was concluded to be the dominant characteristic of phase formation by ion implantation comparing to the conventional thermal process. Amorphous alloy may also be readily formed in ion beam process. The conclusions may be used to direct experiments in general and expected other new phase to be found.
