This paper reports the sliding wear properties and mechanisms of Hadfield high-Mn austenitic steel in a dry-sliding reciprocal tribotest against WC counterpart. The associated were studied through extensive characterisation obtained worn surface using analytical SEM, TEM, XRD micro-hardness test. revealed coefficient scale 10?14 m3·N?1·m?1 friction 0.5–0.6. encountered severe plastic deformatio...

Plasticity in hatching can balance risks of benthic and pelagic development and thereby affect the extent of larval dispersal. Veligers of the nudibranch Phestilla sibogae hatched from their individual capsules if the encapsulated embryos were scattered from a torn gelatinous egg ribbon. Hatching occurred as early as day 4 at 231–251C. The early hatchlings lacked a propodium, swam, and were not...

The flow stress of Hadfield steel is attributed to lattice friction, dynamic strain aging (DSA), mechanical twinning, and forest hardening. However, it has not been clarified yet which mechanism quantitatively contributes most the work Here, an austenitic containing 1.1 wt.% C 12.5 Mn was studied, tensile tests at a rate 1 s−1 were performed neglect DSA effect. friction estimated by Hall–Petch ...
