摘要/Abstract

摘要： 通过观测钨分别在能量密度3.82MJ×m^-2/脉宽5ms和能量密度1.5MJ×m^-2/脉宽1ms的脉冲电子束1~100次的辐照下发生再结晶及晶粒长大的情况，研究了钨在瞬态热流下的再结晶行为及其对脉冲参数的依赖关系。根据非等温匀速加热退火过程的晶粒尺寸表达式推导出了瞬态热流下晶粒正常长大的表达式，再结合实验数据推导出了钨在脉宽ms量级瞬态热流辐照下发生正常长大的晶粒尺寸对脉冲参数的依赖关系。利用该关系计算得到的钨在脉宽5ms、1ms的脉冲电子束辐照下的晶粒尺寸与晶粒只发生正常长大的实验结果相吻合。

Abstract: In order to study the recrystallization behavior of tungsten under transient heat loads and its dependence on pulse parameters, the recrystallization and grain growth of tungsten were experimentally observed under 1~100 pulses of pulse electron beam with the energy density of 3.82MJ×m^-2 at 5ms pulse duration and the energy density of 1.5MJ×m^-2 at 1ms pulse duration. According to the grain size expression of non-isothermal uniform heating annealing process, the expression of normal grain growth under transient heat loads was derived. Combined with the experimental data, the dependence of grain sizes of tungsten under transient heat loads with pulse width of ms on pulse parameters was derived. The calculated grain sizes of tungsten irradiated by electron beam with pulse width of 5ms and 1ms using this formula are consistent with the experimental results that only normal grain growth occurs.

Key words: Pure tungsten, Transient heat loads, Recrystallization, Grain size, Pulse parameters
