| Abstract: | Ultra-purified ferrite stainless steels(UP-FSS)are widely used in the fields of automobile, household appliances etc.Much better performance than conventional ferrite stainless steels is obtained by minimizing the interstitial elements level in UP-FSS.However,some negative effects,such as degradation of the formability and ridging-resistance,are also brought by purifying the steels,which lead to abnormally growth of the columnar grains.Moreover,the grains in heat affected zone(HAZ) are apt to coarsen during... |
