1 引言α-Fe 充氢后既不产生氢化物,也不能在表面形成有效的保护膜,此外很多作者还指出α-Fe 单晶没有不可逆氢脆现象,所有这些都应是讨论α-Fe 中氢时的基本出发点。由于氢能在室温下自由地跑出试样表面,故将氢的状态总地分成室温稳定(RTS)同室温非稳定(RTU)的两部分不无道理。在文献〔5〕中我们又成功地将退火α-Fe同脱C,N α-Fe 的氢致软化(HS)同氢致硬化(HH)现象分成晶内(CL)同晶界(GB)
1 Introduction Hydrogenation of α-Fe after hydrogenation does not produce an effective protective film on the surface, and many authors also point out that α-Fe single crystals have no irreversible hydrogen embrittlement, all of which should be discussed in α-Fe Hydrogen when the basic starting point. Since hydrogen can freely exit the sample surface at room temperature, it is not unreasonable to divide the state of hydrogen into two parts, room temperature stable (RTS) and room temperature unstable (RTU). In [5], we successfully separate hydrogen-induced hydrogen (HH) from hydrogen-induced hardening (HH) of annealing α-Fe and C and N α-Fe into the intragranular (CL)
