This paper deals with the experiment work that the flash cyclicannealing technology of high-speed steel was investigated.
本文介绍了高速钢快速循环退火工艺的研究试验结果，并提出了适合实际生产运用的工艺参数。

The structure of cyclicannealing and isothermal annealing has a little difference, but carbides average size of cyclicannealing is greater than that of isothermal annealing.
循环退火后的组织与等温退火的差异很小，但其碳化物的平均尺寸要大于等温退火。

At lower annealing temperature obtain high strength and high yield ratio showed cyclic softening feature easily. That is detrimental to the using life of coiled tubing.
