The Effect of Plastic Prestrain on Mechanical Characteristics of Titanium Alloys under Static Loading in a Wide Temperature Range

The paper reports the results of an experimental study of the dependences of ultimate strength, offset yield strength, relative elongation, and relative uniform strain of VT 1-0, OT 4-1, and PT 7M titanium alloys on the plastic prestrain value in a temperature range of 290 - 1270 K. The plastic prestrain has been found to considerably affect the mechanical characteristics of titanium alloys in the temperature range from 290 to 770 - 970 K. The highest sensitivity to plastic prestrain is exhibited by offset yield strength and relative uniform strain of the alloys.
