During the turning process of metastable austenitic steels, austenite is transformed into hard martensite by plastic deformation at low temperatures. This enables production components, which have both a hardened subsurface zone and ductile core. Cryogenic cooling allows to be during machining, leads shortening chain. However, effects such as wear can make it challenging adjust properties turni...

Hard turning offers improved manufacturing efficiency but requires great control of the cutting process to achieve required machining-induced surface integrity with respect residual stresses, topography, and near-surface microstructure. This research work is focused on studying effect speed, feed rate, depth cut, chamfer angle, coolant pressure after hard martensitic AISI 52100 steel. The resul...

Dry hard turning (DHT) provides an effective process for finishing high-hardness materials. Machining-induced surface integrity has a direct impact on functional performance. This study compares the effects of DHT and grinding processes machining-induced fatigue performance 18CrNiMo7-6 steel. The experiment were carried out by using polycrystalline cubic boron nitride tool corundum wheel, respe...

The study of Health in All Policies (HiAP) is gaining momentum. Authors are increasingly turning to wide swathes of political and social theory to frame (Program) Theory Based (or Informed) Evaluation (TBE) approaches. TBE for HiAP is not only prudent, it adds a level of elegance and insight to the research toolbox. However, it is still necessary to organize theoretical thinking appropriately. ...
