... °C (1920 to 2100 °F). The extent of alloying is actually governed by the kinetics of second-phase precipitation, the design principle being that the alloys should retain their solution-annealed structures when water quenched and should not suffer continuous grain-boundary precipitation of deleterious...

... in pitting potential with formation of θ phase was explained by the existence of a copper-depleted region near the particles ( Ref 29 ). This region would have a lower pitting potential, so pits would tend to form there first. Another study found that microsegregation of copper and iron impurities at nodes...
