Investigation of electrorefining of metallic alloy fuel onto solid Al cathodes [PDF]

, 2007
This work concerned the electrorefining of UZr and UPuZr alloys on a solid aluminium cathode, in the LiCl-KCl eutectic melt containing U3+, Pu3+, Np3+, Zr2+ or Zr 4+, Am3+, Nd3+, Y3+, Ce3+ and Gd3+ chlorides. During constant current electrolyses, the use

Evidence of aluminium accumulation in aluminium welders. [PDF]

Occupational and Environmental Medicine, 1991
Using atomic absorption spectrometry the aluminium concentrations in blood and urine and in two iliac bone biopsies obtained from welders with long term exposure to fumes containing aluminium were measured. The urinary excretion of two workers who had welded for 20 and 21 years varied between 107 and 351 micrograms Al/l, more than 10 times the ...

Study on the impact wear mechanism and damage modes of compacted graphite cast iron

Journal of Materials Research and Technology, 2022
The impact wear mechanism of compacted graphite cast iron (CGI) at different temperatures (room temperature, 300 °C, 400 °C, and 500 °C) and impact frequencies (10 Hz, 12 Hz, and 14 Hz) was analyzed.

Solid-state NMR characterisation of the thermal transformation of a Hungarian white illite [PDF]

, 2005
1H, 27Al, 29Si and 39K solid-state NMR are reported from a Hungarian illite 2:1 clay for samples heated up 1600 °C. This single-phase sample has a small amount of aluminium substitution in the silica layer and very low iron-content (0.4 wt%).

The Role of Anode Manufacturing Processes in Net Carbon Consumption

Metals, 2016
Carbon anodes are consumed in electrolysis cells during aluminum production. Carbon consumption in pre-bake anode cells is 400–450 kg C/t Al, considerably higher than the theoretical consumption of 334 kg C/t Al.

Clustering and Precipitation during Early-Stage Artificial Aging of Al–Si–Mg(–Cu) Foundry Alloys

Metals, 2023
High-Si aluminum foundry alloys are an important material class for products with complex 3D geometries where casting is the most suitable production method. With Mg and/or Cu additions, these alloys gain strength upon heat treatment due to the formation
