The composition was optimized by tiny alloying, orthogonal test design and the hardness and impacttoughnesstest for the different samples with different combination of alloy composition.
The influence of pre-heating temperature on organization and performance of X80 pipeline steel was investigated by weld thermal simulation technique and the instrumented Charpy impacttoughnesstest.
采用焊接热模拟技术和显微分析方法,研究了回火焊道热处理对X80级管线钢焊接热影响区韧性的影响规律。
