Temperature and strain rate dependence of the mechanical properties of the EPM alloy Ti-35wt.%Al
A #gamma#-based titanium aluminide alloy Ti-35 wt.% Al was prepared by elemental powder metallurgy. Compression and tensile tests were carried out at various temperatures up to 900 C using three strain rates of 10"-"2/s, 10"-"3/s and 10"-"4/s. Metallographic examination of selected specimens was carried out by light microscopy. Due to material flaw...
Changes of heavy metal chemical bonds in thermally treated soils / Aenderung der Schwermetallbindungsformen in thermisch...
The cleaning performance of thermal decontamination methods for heavy metals is reviewed by means of a 8-step sequential extraction process. With the help of this extraction process different soils of varying contents (acidity, proportion of clay, carbonates, C_o_r_g, heavy metals and KAK) are treated thermally at temperature levels of 300 C, 600 C...
