Abstract: Hard turning involves the mechanical deformation of materials, coupled with the heat generation from friction and dissipation of deformation energy. The mechanical and thermal effects on microstructure ...

Abstract: The need for predicting material microstructure and hardness in hard turned surfaces becomes very urgent in that hard turning is adopted by industries as a finishing process, and the produced ...

Abstract: A material softening model based on thermal activation energy has been successfully established through tempering experiments in the first part of this study. To apply the model to predicting ...

Abstract: In literature, four models incorporating strain rate and temperature effects are able to generalize material test results of HY-100 steel. This study compares the four models, namely, Litonski-Batra, ...

Abstract: An investigation was made to compare the performance of a highly loaded transonic turbine stage with and without compound leaned vanes. In both cases, velocity distribution along the vane ...
