Journal ArticleDOI
Grain refined and basal textured surface produced by burnishing for improved corrosion performance of AZ31B Mg alloy
Z. Pu,Guang-Ling Song,S. Yang,José Outeiro,José Outeiro,Oscar W. Dillon,David A. Puleo,I.S. Jawahir +7 more
TL;DR: Grain refinement and strong basal texture were produced on AZ31B Mg alloy surface concomitantly by a newly developed severe plastic deformation (SPD) process, severe plasticity burnishing (SPB), which was attributed mainly to dramatically reduced grain size and strongly basal-textured grain orientation.
Journal ArticleDOI
Enhanced surface integrity of AZ31B Mg alloy by cryogenic machining towards improved functional performance of machined components
Z. Pu,José Outeiro,José Outeiro,António Castanhola Batista,Oscar W. Dillon,David A. Puleo,I.S. Jawahir +6 more
TL;DR: In this paper, the influence of dry and cryogenic machining (liquid nitrogen was sprayed on the machined surface during machining) using different cutting edge radius tools on surface integrity was investigated.
Journal ArticleDOI
Ultrafine-grained surface layer on Mg–Al–Zn alloy produced by cryogenic burnishing for enhanced corrosion resistance
TL;DR: In this paper, an ultrafine-grained surface layer was produced on Mg-Al-Zn alloy by a new severe plastic deformation process, cryogenic burnishing, and the total burnishing-influenced zone was found to be over 3.4mm thick.
Journal ArticleDOI
The effects of Cryogenic Cooling on Surface Integrity in Hard Machining
Domenico Umbrello,Domenico Umbrello,Z. Pu,Serafino Caruso,José Outeiro,José Outeiro,A. D. Jayal,Oscar W. Dillon,I.S. Jawahir +8 more
TL;DR: In this article, the results of an experimental investigation to determine the effects of cryogenic coolant on surface integrity in orthogonal machining of hardened AISI 52100 bearing steel were presented.
Journal ArticleDOI
Finite element modeling of microstructural changes in dry and cryogenic machining of AZ31B magnesium alloy
Z. Pu,Domenico Umbrello,Domenico Umbrello,Oscar W. Dillon,Tao Lu,David A. Puleo,I.S. Jawahir +6 more
TL;DR: In this paper, a preliminary study was conducted to model the microstructural changes of AZ31B Mg alloy during dry and cryogenic machining using the finite element (FE) method and a user subroutine based on the dynamic recrystallization (DRX) mechanism of Mg alloys.
