Achieve high ductility and strength in an Al-Mg alloy by severe plastic deformation combined with inter-pass annealing
Zha, Min; Li, Yanjun; Mathiesen, Ragnvald H.; Bjørge, Ruben; Roven, Hans J. ( Elsevier B.V. , 2014 , Article)Metallic materials processed by severe plastic deformation generally possess very high strength but a rather low uniform elongation, usually <5%. In the present Al-7Mg alloy processed by room temperature equal channel ... -
Dispersion of soft Bi particles and grain refinement of matrix in an Al-Bi alloy by equal channel angular pressing
Zha, Min; Li, Yanjun; Mathiesen, Ragnvald H.; Roven, Hans J. ( Elsevier BV , 2014 , Article)The deformation behavior of a soft particle containing Al-8Bi hypermonotectic alloy during equal-channel angular pressing was studied. The size, shape and distribution of soft Bi particles are substantially modified via ... -
Mechanical properties and surface characteristics of an AA6060 alloy strained in tension at cryogenic and room temperature
Xu, Zebing; Roven, Hans J.; Jia, Zhihong ( Elsevier Ltd , 2015 , Article)Mechanical properties at 77 K and 295 K and surface characteristics of an AA6060 alloy have been studied. The alloy exhibited significant differences in mechanical properties and fracture mechanisms at 77 K in comparison ...
