Available in PDF, EPUB and Kindle. Book excerpt: Many materials processing operations such as age hardening heat treatments typically involve following predetermined time and temperature schedules to obtain the desired final material properties. The intelligent processing approach is to develop sensors for monitoring of material response to processing operations in real time. As an alloy age hardens its electrical resistivity changes. Hence, the process of aging can be monitored by measuring the change in resistivity relative to that of a non-age hardening material such as fully annealed pure aluminum. A device using two small, spiral-wound probes was designed and used to induce eddy currents within the pure aluminum and the aging alloy. The probes were incorporated as elements in an impedance bridge circuit. The bridge unbalance voltage decreased in value over time indicating decreasing resistivity during the aging process. The monitoring concept was verified. Refinements such as improved impedance bridge circuitry and probe size/test frequency optimization are needed to unlock its full potential.

This book was released on 1996-03-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, the design of an eddy current sensor system that continuously monitors age hardening during aging of heat treatable alloys was modified to allow for operation at temperatures up to 595 deg C. With two eddy current coils in an impedance bridge circuit, eddy currents are generated in a pure aluminum reference sample standard and an age harden able test sample. The difference in the resistivity of the aging test sample relative to the reference sample results in a bridge unbalance voltage, Delta V sub BCA, which is continuously measured by a multimeter. Also, calibration procedures were developed to allow conversion of the values of delta V sub BCA to a resistivity difference, Delta p=Ptest - Pref, between the test and reference samples. These calibration curves were generated by measuring delta V sub BCA at various temperatures for six test sample standards of known resistivity. The resistivity of the aging sample is determined by adding the known resistivity value for pure aluminum to Delta p. Real-time monitoring of an aging alloy's resistivity may allow heat treaters to integrate this monitoring system with a control system to achieve 'intelligent heat treating'.
