    Notes:
    A novel method of the velocity measurement of melt was developed on the basis of electromagnetic principles. Two sensors were designed to measure the velocity of melt without direct contact. One, the electromagnetic velocity sensor (EMVS) consists of an electromagnet and a magnetic probe, and the other, the permanent magnet velocity sensor (PMVS) consists of a ring-shaped permanent magnet and a magnetic probe. These velocity sensors were tested with an aluminum cylinder and a Wood metal melt. The magnetic flux densities obtained by the velocity sensors were proportional to the rotating speed of the aluminum cylinder up to 1.5 m/s and the stirring speed of the Wood metal melt up to 0.8 m/s. The calculated magnetic-flux density near the velocity sensor was in good agreement with the measured one. The distribution of the magnetic field of the EMVS was more favorable in obtaining a larger sensor signal than the PMVS. © 2000 American Institute of Physics.

    Notes:
    Abstract Age-hardening characteristics and precipitation behavior of Ag–25%Pd–3%In–1%Zn–0.5%Ir alloy were investigated in detail by means of hardness testing, X-ray diffraction, electron microscopy and resistivity measurement. The solution treating could be accomplished at 980 °C and the aging in the temperature range from 950 to 850 °C occurred by continuous precipitation. The aging in the temperature range from 850 to 450 °C occurred first, forming GP-zones with a hardness increase and then in overaging stage by forming discontinuous precipitation, which consisted of lamellae of solute (Pd, In, Zn) depleted Ag-rich phase and (Pd,Ag)3(In,Zn) intermetallic phase. The hardness increased very fast to its peak in 10 min during aging at temperatures between 450 and 550 °C.
