Effects of Ag on microstructure and mechanical properties

Effects of Ag on microstructure and mechanical properties of 2519 aluminum alloy. This increment at room temperature and 200 C is 24 MPa and 78 MPa, respectively. In contrast, the elongation of 2519 aluminum alloy is decreased with Ag addition. The increase of tensile strength of 2519 aluminum alloy with Ag addition is attributed to the high volume fraction of phase.

Effect of heating rate on microstructure and mechanical

Nov 25, 2014Despite many scholars have studied the effect of heating rate on recrystallization and austenite formation, but the experiments of the effect on final mechanical properties and steel kinds were limited. Thus, the purpose of this study was to observe the influence of heating rate on the final microstructure and mechanical properties of TRIP steel.

Promote Alumina Leaching through Re Pelleting Effects of

The contents of Fe and SiO2 in ferric bauxite are much higher than that in regular bauxite, and the leaching yield of Al2O3 from ferric bauxite cannot reach the general level of ordinary ores, even under optimal conditions. This paper introduces a pretreatment method to enhance sintering before leaching. First, mixing followed by grinding was found to be more efficient than grinding followed
