Hot deformation behaviors of Bi2O3-coated Al18B4O33 whisker reinforced aluminum matrix composite with high formability

Constitutive behavior of Csf/AZ91D composites compressed at elevated temperature and containing a small fraction of liquid

“…The resistance to deformation is lower than that in a solid state at elevated temperature for the reason that the stress concentration or pile-up of dislocations can be released by the liquid phase [9]. Liquid phase can also serve as a lubricant at the interface to improve the reinforcement redistribution which results in a lower work hardening rate [10,11].…”

Influence of extrusion temperature on deformation behavior of Csf/AZ91D composite during semi-solid extrusion

“…The simulated results of the deformation behavior in semi-solid zone are not accurate enough. Recently, deformation behavior in semi-solid state has been investigated by compression tests [9][10][11][12][13]. It suggests that mechanisms of deformation are strongly affected by the volume and distribution of a liquid phase.…”

Tensile properties of an aluminum matrix composite reinforced by SnO2-coated Al18B4O33 whisker

“…Researchers also indicated compressive fl ow stress in Bi 2 O 3 -coated ABO whisker reinforced aluminum composite was decreased by the Bi 2 O 3 coating [10] , and the formability of the composite was improved, which was considered as the result of low melt point of Bi induced by interfacial reaction between the coating and matrix. Up to now, the studies on the hot deformation behaviors of WRAMCs have usually been related to the compressive deformation [11] , because whiskers can bear much larger compressive strain than tensile strain. However, it is difficult to obtain the detail fracture mechanism information of the composite through compressive deformation experiments.…”
