Microhardness Gradients and Structural Phase States of the Coating Contact Zone (HEA CoCrFeNiAl) with Substrate (Alloy 5083)

Известия Алтайского государственного университета
A non-equiatomic high-entropy alloy (HEA) CoCrFeNiAl coating on the 5083 alloy substrate is produced by wire-arc additive manufacturing (WAAM). It is revealed that microhardness changes significantly at the contact zone of the "coating — substrate ...

Single Independent Autopolyploidization Events From Distinct Diploid Gene Pools and Residual Sexuality Support Range Expansion of Locally Adapted Tetraploid Genotypes in a South American Grass

Frontiers in Genetics, 2021
Polyploidy plays a major role in plant evolution. The establishment of new polyploids is often a consequence of a single or few successful polyploidization events occurring within a species’ evolutionary trajectory.
