摘要

随着二氧化碳减排的要求，超快加热（UFH）热处理工艺的使用在过去几年引起了极大的关注。本文报道了AISI441铁素体不锈钢的超快速加热（UFH）处理效果。结果表明，为了获得完全再结晶的微观结构，需要975°C的最低温度。该研究强调了超快退火对晶粒尺寸演变的影响，这是不同工艺参数的函数。所获得的微观结构与极限拉伸应力和硬度方面的机械性能有关。

EFFECT OF ULTRAFAST HEATING ON AISI 441 FERRITIC STAINLESS STEEL

The use of the ultrafast heating (UFH) heat treatment process attracted great attention in the last few years, following the requirements of CO2 emissions reduction. The effect of ultrafast heating (UFH) treatment an AISI 441 ferritic stainless steels is reported in this paper. Results show that a minimum temperature of 975 °C is required in order to achieve a fully recrystallized microstructure. The study highlights the effect of ultrarapid annealing on grain size evolution as a function of different adopted process parameters. The obtained microstructure is related to mechanical properties in terms of ultimate tensile stress and hardness.
