根据平整试验之后制成的标准拉伸试样 ,测定了奥氏体不锈钢 0 Cr18Ni9薄板和铁素体不锈钢1Cr17薄板在不同平整量下的基本成形性能指标 ,给出了相应的趋势线和线性回归方程及其相关系数。试验结果反映了基本成形性能指标随平整量的变化规律。平整量 et∈ [0 ,5 ) ,满足工程要求 ,并当 et=2 %时基本成形性能最优。并对此结果作了解释 According to the standard tensile test made after the flattening test, the basic forming performance indexes of austenitic stainless steel 0Cr18Ni9 sheet and ferritic stainless steel 1Cr17 sheet under different flattening amount were measured, and the corresponding trend line and linear regression Equation and its correlation coefficient. The test results reflect the change rule of the basic formability index with the flat quantity. The leveling quantity et ∈ [0, 5) satisfies the engineering requirements and the basic formability is optimal when et = 2%. And explained the result
