11、he process of reducing thevolume fraction of inclusions or modifying the shape ofinclusions to improve formability, weldability, and machinabil-ity.3.2.2.1 DiscussionInclusions, especially those elongatedduring the rolling process, create the conditions for initiating orpropagating cracks when the m
12、aterial is stretched or bentduring the manufacture of a part (or both). The adverse effectsof inclusions are minimized by reducing the content ofinclusions in the steel or by altering the shape of inclusionsthrough the use of additions during the steelmaking processthat change the elongated shape of
13、 the inclusions to lessharmful small, well dispersed globular inclusions (or both).1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved
