Abstract:
1. A method of automatically quantifying dendrite arm spacing in a dendritic microstructure of a cast aluminum-based material, said method comprising: providing a computer-based system comprising an input, an output, a central processing unit and memory; introducing program code into at least one of said input, memory and central processing unit from a computer-readable medium having a non-transitory form of said program code embodied therein; operating said program code such that calculations made thereby are performed by said central processing unit; selecting from said cast aluminum-based material a location of interest that is possessive of said dendritic microstructure; using said system to automatically analyze said location of interest to quantify a dendrite cell size therein; and using said program code to convert said quantified dendrite cell size into a quantified dendrite arm spacing through at least one of (a) an empirical relationship between said dendrite cell size and said dendrite arm spacing that is expressed by DAS=a*DCS+b, where a and b are material constants particular to said cast material and (b) a theoretical relationship between said dendrite cell size and said dendrite arm spacing that is expressed by DAS=1−V
