摘要:

用电子束熔炼法合成的锆样品,研究了锆在4.2K温度下拉伸变形,然后加热到室温300K,对锆晶体栅结构和超导转变温度Tc的影响。在我们看来,登记的临界温度Tc的大幅增加(20%)是在塑性形变区域中的超导性增强的结果在孪生边界的锆晶体光栅和有效的改变的电子间的吸引力常数的大小。

英文摘要:

We have researched the effect of the zirconium deformation by the extension at the temperature of 4.2 K, with the subsequent heating up to the room temperature of 300 K, on both the zirconium crystal grating structure and the magnitude of superconducting transition temperature Tc, using the zirconium samples, synthesized by the method of the electron beam melting. In our opinion, a registered substantial increase of the critical temperature Tc (by 20%) is a result of both the superconductivity enhancement in the plastic deformation regions at the twin boundaries of the zirconium crystal grating and the effective change of the inter-electron attraction constant magnitude.
