چکیده انگلیسی
This paper summarizes and highlights recent advances in developing novel manufacturing techniques involving cryogenically-assisted processing (machining, burnishing and friction-stir processing) on a range of aerospace, automotive and biomedical metal alloys (Co-Cr- Mo, AZ31BMg, NiTi, Inconel 718, SS 303 stainless steel, and Al 7050) for achieving enhanced product quality, life and performance at component level. This study presents an analysis of surface integrity involving severe plastic deformation (SPD) of these materials induced by cryogenically-assisted manufacturing processes, by showing the resulting product/component performance enhancement through the generation of controllable ultra-fine/nano grain structures in the surface layers of the products/components. This grain refinement is also often accompanied by improved wear and corrosion resistance properties and the generation of compressive residual stresses enabling improved fatigue life, along with more favorable phase transformation in these cryogenically-processed materials. Experimental results are compared with predictions obtained from numerical models and simulations. Encouraging trends are observed with potential for applications in industry.
