Twinning induced plasticity steels are austenitic alloys in which mechanical twinning is a prominent deformation mode, and which exhibit exceptional combinations of ductility, work hardening and ultimate strength. The authors develop in the present paper a crystallographic theory to enable the quantitative investigation of the role of mechanical twinning in enhancing the properties of these all...

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...
