摘要
１前言应力腐蚀裂缝至今仍然是焊制容器失效的重要原因之一。为防止应力腐蚀裂缝，通常采用焊后热处理，局部焊后热处理时，主要控制参数是：均热，加热和保温区的宽度。均热区应达到所要求的温度以及容许的温差范围，且不得超过规定的最高温度，它包括焊缝，热影响区以及...
Abstract A series of different local PWHT conditions are studied to find the critical heated widths based on creep FEM analysis and it is found that a heated width of 2 5rt on either side of welds seems reasonable.
