Effects of quenching agents, two-step aging and microalloying on tensile properties and stress corrosion cracking of Al-Zn-Mg-Cu alloys

open access: yesJournal of Materials Research and Technology, 2020
In this paper, the tensile properties and stress corrosion resistance of two Al-Zn-Mg-Cu alloys were tested by tensile test and slow stress rate tensile test. The microstructures of the precipitation were observed by transmission electron microscopy, and

Characterization of Nanosized Carbide Precipitates in Multiple Microalloyed Press Hardening Steels

open access: yesMetals, 2023
Press hardening steel standardly relies on titanium microalloying for protecting boron from being tied up by residual nitrogen. This practice safeguards the hardenability effect of boron during die quenching.

Grain Size Evolution and Mechanical Properties of Nb, V–Nb, and Ti–Nb Boron Type S1100QL Steels

open access: yesMetals, 2021
Titanium additions are often used for boron factor and primary austenite grain size control in boron high- and ultra-high-strength alloys. Due to the risk of formation of coarse TiN during solidification the addition of titanium is limited in respect to ...
