英文摘要
Solid-phase bonding at low temperature was carried out in pure Fe with ultrahigh density lattice defects formed by HPT (high-pressure torsion) - straining which is one of severe plastic deformation processes. The tensile strength, TS, in the HPT-processed (HPTed) Fe was TS 1.4 Gpa, and also kept the high strength of TS 1.0 Gpa after annealing at 300 ℃. The solid-phase bonding of the HPTed Fe and the HPTed Fe specimens occurred slightly at 300 ℃. On the other hand, the HPTed Fe and the non-HPTed Fe specimens could not be bonded at 300 ℃.
