Effect of the Heat Affected Zone Hardness Reduction on the Tensile Properties of GMAW Press Hardening Automotive Steel by Alfredo E. Molina-Castillo, Enrique A. López-Baltazar, Francisco Alvarado-Hernández, Salvador Gómez-Jiménez, J. Roberto Espinosa-Lumbreras, José Jorge Ruiz Mondragón, Víctor H. Baltazar-Hernández

“…An ultra-high-strength press-hardening steel (PHS) and a high-strength dual-phase steel (DP) were butt-joined by the gas metal arc welding (GMAW) process, aiming to assess the effects of a high heat input welding process on the structure-property relationship and residual stress. The post-weld microstructure, the microhardness profile, the tensile behavior, and the experimentally obtained residual stresses (by x-ray diffraction) of the steels in dissimilar (PHS-DP) and similar (PHS-PHS, DP-DP) pair combinations have been analyzed. …”

Effect of rice husk ash content and carbonization curing on lime-stabilized recycled aggregates: mechanical behavior and microscopic mechanism by Haocheng Lai, Kaihao Lin, Na Li, Junyi Qin, Yifang Song, Yiming Jiang, Wei Wang

“…The main findings are as follows: (1) Both RHA and carbonation treatment significantly improve the UCS of lime-stabilized recycled aggregates, with optimal RHA content and carbonation time identified as 6% and 12 h, respectively. (2) RHA and carbonation treatment do not alter the chemical composition of RLA but promote the formation of C–S–H gels and CaCO _3 . (3) The combination of RHA and carbonation treatment enhances the densification of C–S–H gels in RLA; however, excessive carbonation results in decalcification of the C–S–H gel, which reduces the calcium-to-silicon ratio of RLA. (4) Both RHA and carbonation treatment contribute to reducing porosity and improving microstructure of RLA. However, excessive carbonation leads to an increase in porosity and a deterioration of the microstructure of RLA. …”
