However, the FSP of die casting alloys has not previously been reported. Inthisstudy,themulti-passFSP(MP-FSP)technique[18,19] was performed using an ADC12 aluminum die casting alloy to obtain a wide-area improvement, and the mechanical properties of the MP-FSP samples were evaluated. Particularly, the effects Defects in Rolled Products a) General b) Operational a) General The defects may arise due to i)Surface irregularities: The ingot or the raw material may be having irregularities due to scaling which will get trapped in the metal and remain inside the metal surface as laps. This needs to be removed by grinding and there will be metal loss. A casting qualified to higher casting specification level will also qualify for lower casting specification levels (e.g. CSL-4 is qualified for CSL-3, CSL-2 and CSL-1). Repair welding on the qualification casting is to comply as per Table 2 below. Cosmetic grinding to remove defects is permitted, but is to be kept to a minimum.
