There is considerable interest in improving the resistance of fully austenitic TWIP steels to hydrogen embrittlement; one potential route use V additions promote trapping by V(C,N) precipitates. This has dual benefit increasing yield strength through precipitation strengthening and grain refinement. However, effect on slab quality during continuous casting not been determined. In this study, ho...

A, survival analysis regression model is described for analyzing twip. data on the age-atmenarche. The model includes latent genetic and environmental covariates and allows one to test hypotheses regarding the nature of familial aggregation for age-at-onset. Additionally, the model accommodates a variety of baseline survival distributions and therefore may be used to test different developmenta...
