Investigation on the hot ductility of Q235 low-carbon steel with boron addition

open access: yesResults in Physics, 2019
We tested the mechanical properties of B-containing steel at 600–1300 °C using Gleeble 1500, and the hot ductility was investigated according to the reduction in area (RA). The fractured specimens were examined using scanning electron microscopy.

Effect of Tin on Hot Ductility and High-temperature Oxidation Behavior of 20CrMnTi Steel

open access: yesHigh Temperature Materials and Processes, 2014
The hot ductility and high-temperature oxidation behavior of 20CrMnTi steel with 0.02% Cu and x% Sn (0.004 ⩽ x ⩽ 0.049) were investigated. The results show that tin has no significant effect on tensile strength of sample with less than 0.049% Sn.

When Mechanics Rewrites Chemistry: Divergent Pathways of Hardening and Softening in High Strength Al-Alloys. [PDF]

open access: yesAdv Sci (Weinh)
Mechanics reshapes chemistry: plastic flow actively governs two divergent, atomic‐scale mechanochemical pathways that tailor strain localization and ductility in high‐strength 7xxx Al alloys. Rather than relying on static structures, deformation dynamically reinforces the solution‐treated state via clustering, yet destabilizes the peak‐aged condition ...
