Abstract: In the present study, work-hardening behavior under various loading paths of a commercially pure titanium JIS Grade 1 sheet was investigated. The following tension-compression asymmetry was presented. The yield stress was smaller under compression than under tension, whereas the subsequent work-hardening was larger under compression than under tension. When the sheet was subjected to reverse loading from compression to tension, strong Bauschinger effect was exhibited. Thereafter, a concave curve followed by a small stress peak appeared, which was not presented under monotonic tension. Microstructure observations suggested that this characteristic behavior would be owing to the the activities of twinning and detwinning respectively during compression and following tension.
