I have been repairing blocks of 5120H in an extremely high fatigue application, (they hold a 120 kg steel component which oscilates at around 300 cycles per minute),weight is around 150-200 kg per block.
They are originally toughened and hardened (to approximately 63 rockwell) , and i need to...
I am after information on embrittlement in aluminium structures (marine and aircraft) due to thermal cycling , ie night / day .....winter /summer conditions.
(both in welded and mechanicaly fastened structures)
and also embrittlement patterns due to age
I realise that this is a very wide...
