Strain age embrittlement

Strain age embrittlement

Strain age embrittlement

(OP)
Has anyone experience strain-age embrittlement on thick plates (3" (75mm)or greater) in the HAZ?  No cold working was done on our plates, so it would all have to come from the welding.  We are trying to determine if this is a possible cause of low HAZ tougness values for some testing we are currently doing to qualify some base metal at high and low heat input, and we only have the low values at the low heat input, which is reverse of most experiences.

RE: Strain age embrittlement

Try the TWI website www.twi.co.uk they have lots of FAQ's on issues like this.
