Effect of Mn-Content on the Deformation Behavior of Binary Ti-Mn Alloys
The effect of Mn-content on the deformation of Ti-Mn low cost alloy system was investigated. A set of alloys ranging in composition from 8 to 20 %wt Mn were produced. The alloys were subjected to solution heat treatment at 900 °C. Existed phases were evaluated through XRD and microstructure observation. The cold workability and the change in micro-hardness were studied. The results showed that β-phase is predominant in all alloys under study. Lower Mn-content alloys had poor cold workability, but higher Mn-content showed a drastic improvement reaches to around 95% cold working until certain composition then dropped. Change in micro-hardness with the Mn-content is hardly observed. On the other, the strain hardening effect generated from cold working enhances the micro-hardness significantly.
