In addition to demonstrating a high degree of alignment of both the iPP b-axis and the talc c-axis parallel to the sample wall normals, thus corroborating earlier reports, the synthesized maps also yield new insights into the molecular organization.
The magnetic field is applied either perpendicular or parallel to the sample surface that means in case of the investigated samples in easy axis or hard axis direction (parallel or perpendicular to the pores).
Fig. 1 Scheme of placement of Cu-Al-Mn alloy samples at annealing: a without a field; b in the magnetic field perpendicular to the main axis of sample; and c in the magnetic field parallel to the main axis of sample, where 1 is an electrical heater, 2 is a sample, 3 is a thermocouple, and 4 is а magnetic pole.
The weakest magnetic field that will cause this transition is called the critical field (Hc) if the sample is in the form of a long, thin cylinder or ellipsoid and the field is oriented parallel to the long axis of the sample.
The shear wave oscillates parallel to the axis of the sample.
After the homogenizing annealing at 1123 K for 10 h, the alloy samples were quenched in water and then annealed in air at 473 K for 3 h in magnetic field with intensity of 1.5 kOe having different orientation (perpendicular or parallel to the main axis of sample) or without field.
Fig. 1 X-ray diffraction patterns of Cu Al Mn alloy samples annealed at 200 °C for 3 h without magnetic field (a), in magnetic field perpendicular to the main axis of a sample (b), and in magnetic field parallel to the main axis of a sample (c).
Permeability measurements were made by flow of helium gas through the samples parallel to the plug axis.
The same type of damage was observed at RT and at 300 °C with the only difference that more damage takes place at RT. Fig. 9a d show characteristic light optical micrographs of cross-sections parallel to the compression axis for samples of AlSi10Cu5Ni1 and AlSi10Cu5Ni2 deformed at 300 °C in the AC and 4 h ST conditions, respectively.
