基于Master Curve方法的Q345R钢断裂韧性研究
Estimation of Q345 R Fracture Toughness Based on Master Curve
摘要
Abstract
Tensile test,Charpy impact test and drop-weight test of Q345R steel in the ductile-brittle transi-tion range were carried out.Master Curve method was developed by single-temperature and multiple-tem-perature method respectively,and compared with the empirical equations adopted in ASME,API and BS. Results show that the reference temperature T0 derived from single-temperature and multi-temperature method is basically consistent,and is about -105 ℃.Master Curve can well envelop the fracture tough-ness and temperature curves derived from the empirical equations,and be more economic and flexible than the KIC curve with sufficient conservation.关键词
