摘要

为研究高应变速率下绝热温升与应变速率对FA超高强钢应变诱发马氏体相变的耦合影响机制，对传统分离式霍普金森拉杆（Split Hopkinson Tensile Bar，SHTB）装置进行改进，通过增设能量吸收杆和动量捕获套管，解决传统SHTB试验中的多脉冲加载干扰问题，成功开发单脉冲加载技术。基于此项试验技术改进，创新性地提出有效解耦的试验方案：通过应变增量试验（准等温加载）实现对绝热温升效应的有效分离，量化分析应变速率的影响，进一步结合应变受控试验（非等温加载），量化分析绝热温升的影响。通过绝热温升与应变速率对应变诱发马氏体相变含量的抑制影响权重对比，揭示出绝热温升对应变诱发马氏体相变含量的抑制作用占据主导地位，而应变速率的增加仅有限提升其抑制效果。

Abstract

The coupling effect mechanisms of adiabatic temperature rise and strain rate on strain-induced martensitic phase transformation in FA ultra-high-strength steel under high strain rates are investigated. The traditional split Hopkinson tensile bar (SHTB) apparatus is improved by adding an energy absorption bar and a momentum capture sleeve

thereby addressing the issue of multipulse loading interference in conventional SHTB tests and successfully developing a single-pulse loading technology. On the basis of this experimental technique improvement

an innovative decoupling experimental scheme is proposed. In the scheme

the adiabatic temperature rise effect is effectively separated through strain increment tests (quasi-isothermal loading)

and the influence of the strain rate is quantitatively analyzed. Furthermore

the influence of an increase in the adiabatic temperature is quantitatively analyzed through strain-controlled tests (non-isothermal loading) . The inhibitory effects of adiabatic temperature rise and strain rate on the strain-induced martensitic phase transformation content are compared. It reveals that the inhibitory effect of adiabatic temperature rise on the strain-induced martensitic phase transformation content is dominant

whereas an increase in the strain rate only marginally enhances its inhibitory effect.
