摘要
运用“灰色系统”理论的关联分析法对Wel-ten80c 80kg级低合金高强钢焊接过热区韧性的变化规律进行了分析。采用关联度(R)的概念较科学地确定了最佳工艺参数t_(3/5)。
The toughness changed pattern in overheating zone of HSLA Wel-ten 80c steel, σb=8Okg/mm^2, welded joint has been studied with correlative analysis method of 'gray system theory'. The optimum process parameters t_(8/5) is determined reasonably using the concept of correlativity (R).
