An automated containerless processing system to directionally solidify high temperature reactive materials has been previously described (1). The software used for control has: been simplified and improved over that previously reported. Temperature has been eliminated as a necessary control variable for the directional solidification process. All proportional and integral (PI) control is based upon image processing using parallel processing software. Control actions can occur several times a second using a DEC 11/23+ computer assisted by two PC's. The system has since been used to produce high-purity bulk metallurgical samples of high melting intermetallic compounds, single crystals grown from oriented seeds, and new polyphase intermetallic/metallic in-situ composites. New characteristics of the process are described; and properties of recently produced materials reviewed and related to current high temperature materials. |
