Advanced Materials Research, 2012 In this paper, the relationship between the tensile ductility loss and the conditions including the exposure process and microstructures for the hot exposed TiAl alloys was researched. The critical temperature corresponding to the ambient tensile ductility loss to 0.8% was sensitive to the microstructure.

The Mechanism of Hot Ductility Loss and Recovery in Nb-Bearing Low Alloy Steels [PDF]
Metallurgical and Materials Transactions A, 2014 In low alloy steels containing Nb, the poor hot ductility is basically due to the austenite grain boundary segregation of sulfur and the additional matrix strengthening of Nb(C,N) precipitates, both of which decrease the equicohesive temperature. The recovery of hot ductility is therefore attributed to not only the clean grain boundaries that the ...

ISIJ International, 2004 Strand surface cracking is a problem that can lead to scrap the product of the continuous casting process. Stress and strain developed during continuous casting have been found to be effective in this respect. The crack susceptibility is usually evaluated by assessing the steel hot ductility at the straightening stage of the process.
