Major stuck on a question for my assignment, totally wracked my brain and my mates too! here is the qtn(adsbygoogle = window.adsbygoogle || []).push({});

An alloy has an initial shear yield strength. After ageing to an overaged condition the matrix now contains particles where the average centre to centre spacing is 275nm. The average partical diameter is 75nm. Determine the new strength of the alloy taking into account the strengthing contribution from the disperesd particles.

Data

Burgers vector the dislocation= 0.286nm

shear modulas of the alloy 80GPa

We have worked out the addiitional strenght but cant seem to work out the initial to add it to the additional to work out the new!

Please please, anybody... help me
