高压下黄铜中追赶稀疏波速度的辐射测量
RADIOMETRIC MEASUREMENTS OF OVERTAKING RAREFACTION WAVE VELOCITIES IN SHOCK-LOADED BRASS UNDER HIGH PRESSURES
【摘要】 用光辐射法、以有机玻璃作窗口测量了143-182GPa H62黄铜的追赶稀疏波速度。给出了在对称碰撞下,用透明材料作窗口时,实验确定追赶稀疏波速度的公式。安验结果表明,H62黄铜的冲击熔化点在143-162GPa之间。
【Abstract】 Overtaking rarefaction velocities in shock-loaded H62 - brass were measured by using radiometry in the pressure range from 143-182 GPa, and the PMMA were used as the window material. Formulae for determing the overtaking rarefaction velocity are given in case of a symmetrical impactiori . The experimental results showed that the shock melting in H62-brass are occured in the region between 143 and 162GPa.
