Scale scars through too long annealing time - 1.4305

 

Because of unfavorable parameter during the solution annealing, too high temperature or too long holding time, strong scale layers can be formed. This scale layer is partly accompanied by stronger formation of scars. Unless by wrongly selected annealing parameters, a furnace disturbance yields the same defect picture.
