Abstract: The magnetocaloric effect of Fe91−xMo8Cu1Bx (x=15,17,20) amorphous alloys has been studied. The temperature of the peak of magnetic entropy change can be tuned by altering the Fe∕B ratio in the alloy, without changing its magnitude, ∣ΔSMpk∣. The average contribution of the Fe atoms to ∣ΔSMpk∣ increases with increasing B content. This is correlated with the increase in the low temperature mean magnetic moment of Fe. A recently proposed master curve behavior for the magnetic entropy change is also followed by these alloys and is common for all of them.

TL;DR: The effect of both longitudinal and transverse magnetic field applied during the heat treatment on the magnetic properties of HITPERM-type (Fe 1 - x Co x ) 81 Nb 7 B 12 ( x = 025, 033, 05, 066, 075 ) alloys has been investigated in this paper.

TL;DR: In this article, the authors used the technique of rapid quenching from the melt (planar flow casting method) to prepare active brazing Ag-Cu-Ti alloys with varying Ag and increased Ti content for joining alumina ceramics in form of ribbons 0.1mm thick and 40 mm wide.

TL;DR: In this paper, optical microscopy and X-ray diffraction were used to check the microstructure of as-quenched and annealed ribbons (800C/24 h and 72 h).

TL;DR: In this article, the experimental reinvestigation of the Al-Co phase diagram in vicinity of Al 13 Co 4 family of phases was focused on the experimental reuse of the as-cast alloys with bulk compositions ranging between Al 71 Co 29 and Al 77 Co 23.
