When in a strain state, molybdenum alloy sheets exhibit distinct anisotropy of mechanical characteristics. The anisotropy of elastic, strength, and plastic characteristics is due to crystallographic and structural textures formed in the alloys in the course of rolling.
The highest yield strength values, irrespective of the molybdenum alloy chemical composition, are noted in specimens cut transverse to the rolling direction. As to plasticity characteristics, no clear relationship is observed.
For some alloys the maximum values of elongation are achieved in the specimens cut out in the rolling direction, while for the others an angle of 45° to the rolling direction. A tensorial criterion is put forward which allows description of the total curve of strength or elasticity characteristics in the plane of the sheet.
The textural analysis has failed to give any positive results in describing the curve of yield-strength anisotropy but it can provide a fairly accurate description of the elastic modulus behavior.
