Zr, Nb, and Ta as alloying elements for Ti alloys are important for attaining superior corrosion resistance and biocompatibility in the long term. However, note that the addition of excess Nb and Ta to Ti alloys leads to higher manufacturing cost. To develop low-cost manufacturing processes, the effects of hot-forging and continuous-hot-rolling conditions on the microstructure, mechanical prope...

Musculoskeletal disorders (MSDs) are common health problem throughout the world. Assessment of exposure levels to MSD risk factors can be an appropriate base for planning and implementing interventional ergonomics programs in the workplace. The presents study is focused on posture analysis of the workers working in forging industry. The study was conducted on 130 workers engaged in various proc...

A new near-net forging procedure of titanium and alloys was proposed by using a carbon-supersaturated punch die. Due to the in situ formation carbon-based tribofilm on contact interface between dies work materials, low frictional state sustained through process even high reduction thickness. The hardening suppressed during forging; an additional annealing unnecessary whole forging. Pure ?-phase...
