... created by slip-induced breakdown of submicron strengthening particles, which occurs more readily at high strength levels ( Ref 8 ). If the strengthening (matrix) precipitates are shearable they may promote strain localization which leads to premature crack nucleation and low fracture toughness. Whether...

... of the interaction ( Ref 26 ). When dislocations encounter strong obstacles, such as nonshearable precipitates, along its slip plane, they must bow through large angles in order to break away and bypass the obstacles and continue gliding. Weak obstacles, such as solute atoms or small, shearable precipitates...

... on the development of yield strength indicate that the strengthening contribution from shearable and nonshearable precipitates is proportional to the squareroot of the precipitate volume fraction ( Ref 35 ). Quench factor analysis contradicts this experimentally verified result. It is suggested that the following...
