Tensile deformation behavior of TRIP-aided bainitic ferrite steel in the post-necking strain region

open access: yesScience and Technology of Advanced Materials: Methods, 2021
Transformation induced plasticity (TRIP) steels present a remarkable balance of strength and ductility. However, their post-necking hardening behavior, which is required for press-forming and automobile crash simulation, is unreliable because of their ...

Hardening of an Al-Cu-Mg alloy containing type I and II S phase precipitates

open access: yes, 2010
The effect of different thermo-mechanical treatments on the hardness of the 2024 (Al-Cu-Mg) alloy was studied. Artificial ageing was conducted through heating at a constant rate to specific temperatures followed by rapid cooling.

Critical Role of the Cortical Alveolus Protease Alveolin in Chorion Hardening In Vivo at Medaka Fertilization

open access: yesBiomolecules, 2023
Alveolin is a cortical alveolus proteinase that is secreted in the perivitelline space (PVS) at fertilization to act on the chorion. Purified alveolin is known to induce chorion hardening in vitro by processing zona pellucida B (ZPB), a major chorion ...
