通过充氢后的金相表征和测氢研究了高压扭转（HPT）对 Fe-0.01mass% C 和 310S 不锈钢中氢捕获的影响。 HPT 加工后两种材料的硬化是通过晶粒细化实现的。由于氢与体心立方铁中的位错和晶界等晶格缺陷的结合能较高，HPT 处理显着增加了 Fe–0.01mass% C 中的氢捕获。在HPT处理的310S型中，位错捕获的氢含量小于晶格内溶解的氢含量，并且晶界对氢捕获的贡献可以忽略不计。在HPT加工的稳定奥氏体不锈钢中，降低位错密度可以将捕获的氢减少到固溶处理的水平，同时保留晶粒细化带来的硬化。
The effect of high-pressure torsion (HPT) on hydrogen trapping in Fe–0.01mass% C and type 310S stainless steel was studied by metallographic characterization and hydrogen measurement after hydrogen gas charging. Hardening of both materials after processing by HPT was achieved through grain refinement. Hydrogen trapping in the Fe–0.01mass% C was significantly increased by HPT processing, because of high binding energies of hydrogen with lattice defects such as dislocations and grain boundaries in body-centred cubic iron. In the type 310S processed by HPT, the hydrogen content that trapped by dislocations was less than that dissolved within the lattice and the contribution of grain boundaries on hydrogen trapping can be neglected. In the stable austenitic stainless steel processed by HPT, decreasing the dislocation density can reduce the trapped hydrogen to the solution-treated level while the hardening by grain refinement is retained.
