    quenching aluminium in salt baths

    I was thinking today about another post, when someone asked if aluminium was corrosive. I replied that salt water is coroosive to aluminium. I am now thinking if this is so, why do people use oltem salt baths as a quenching medium, surely this promotes corrosion, especially along grain...

    Aimed at uk based metallurgists.

    I need some information on tensile testing of LM6, we consistently obtain results that are lower that that stated in alars book of 190 uts 80 proof and 7% elongation. I need to know is anyone has tested LM6 Chill, and obtained results higher than these?

    Lower mechanical properties

    I have reason to test an Aluminium alloy, grade LM6 as cast. No originally we took test bars from the casting and these were lower than the limits laid down of 80n/mm2 proof, 190 tensile stress 7% elongation. we originally though that due to the fact that the material was removed from the...

    Some boffin work required

    Okay this is an unusual one. We have a casting that i want to see what happens when i impact it. Now my plan isnt complicated (just as well), but i plan to use an steel 'H' beam and drop it from a height. I want to measure simply (no need to include air resistance, wind drift and the like )...
