The role of defect size on the fracture toughness of powder processed Ti-10V-2Fe-3Al

A CPFEM based study to understand the void growth in high strength dual-phase titanium alloy (Ti-10V-2Fe-3Al)

“…A crack growth model along the grain boundary 𝛼 was presented based on various parameters like grain size, yield strength, plastic zone size, and crack deviation by Terlinde et al (1988). The effect of microstructural defects and inclusion in powder-processed Ti-10V-2Fe-3Al alloy in fracture toughness was studied by Moody et al (1989), it was found that the small inclusions do not participate in fracture process whereas the inclusions which partook in fracturing grew in size and became the void nucleation sites as per ductile fracture theory. Zeng & Zhou (1999) studied the effect of 𝛽 flecks as the possible crack nucleation site in Ti-10V-2Fe-3Al.…”

Contribution of deformation-induced martensite to fracture appearance of austenitic stainless steel

“…The connectivity between dimple size distribution/number densities and precipitate size/shape distribution has been established for a number of alloys reported by Goods and Brown in their elegant study. 6 Garrison et al 5,8,[15][16][17] experimented and reviewed the ductile fracture mechanisms of various alloys with fine scale microstructure and different void nucleation characteristics of steels/other alloys in their research works. The present author has already confirmed the correlation between mechanical properties and the micro void features of a ductile fracture for different alloys under unlike circumstances documented elsewhere.…”
