Abstract

Abstract:

Uniaxial diffusion welding (U-DW) technique was used to solve channel deformation in fabrication of water cooled ceramic breeder (WCCB) blanket on China Fusion Engineering Test Reactor (CFETR). Under the optimized welding condition the flat-type first wall mockup with cooling channels was fabricated by using two-step hot isostatic pressing diffusion welding (HIP-DW). The experimental results show that the temperature of solid phase bonding needs to be higher than 950℃, and the mechanical properties of post-weld samples can be effectively recovered with tempering at 760℃ for 60 minutes.

Key words: CFETR WCCB blanket, Cooling channel dimension control, Hot isostatic pressing diffusion welding, Uniaxial diffusion welding

摘要：

针对CFETR水冷包层流道钢构件热等静压制备时易变形压塌问题，利用单轴扩散焊设备开展了焊接工艺参数优化试验。在此基础上，重新设计了流道焊接界面位置和尺寸，用两步热等静压扩散焊法制备出了流道变形可控的平板型第一壁钢构件模块。优化试验表明，低活化钢试样的固相扩散焊温度需高于950℃，焊后经过760℃/60min回火热处理试样力学性能可以得到有效回复。
