Effect of cooling velocity on phase transformation and formation of steel t 91相變速度和產(chǎn)物的影響
Thermal creep velocity 熱蠕變速度
The contravariant velocity fluxes are used as the dependent variables in the paper . the discretization equations were sieved using the simple , simplec and simpler algorithms 選取曲線坐標(biāo)系下逆變速度通量分量為獨(dú)立變量,由水位校正法求解水位流速耦合問題。
2 . the creep data were processed and analyzed with mathematical method . based on the experimental results , curve of creep rate versus stress and of creep rate versus temperature were curved 用最小二乘法對蠕變速度與應(yīng)力及蠕變速度與溫度- t的幾組蠕變數(shù)據(jù)進(jìn)行擬合,得到相應(yīng)的方程。
