GE Identification of Common Metals

General Electric

General Electric Corp. developed an expert system to identify common metals and alloys. The user is asked to supply information on density, color, hardness and simple chemical tests that can be performed by non-metallurgists in a non-laboratory setting. If sufficient information is available, the system will positively identify the metal or alloy. If there is not sufficient information, the system will provide a list of possible metals in order of likelihood.
