Portevin-Le Châtelier Effect in a Powder Metallurgy Co-Ni-Based Superalloy

Portevin-Le Châtelier Effect in a Powder Metallurgy Co-Ni-Based Superalloy

The Portevin-Le Châtelier (PLC) effect in a powder metallurgy (PM) Co-Ni-based superalloy was systematically investigated via the tensile tests at temperatures ranging from 200 to 600◦C and strain rates at 1.0 × 10−4 to 1.0 × 10−2. Both normal and inverse PLC effects were observed in the PLC regime...
