Abstract

The influence of interlamellar spacing (λ) and heat-treatment on the compressive deformation of unidirectionally solidified Cd-Zn eutectic alloys has been investigated by precision strain measurements during compressive loading and by optical and transmission electron metallography. The flow stress at a measured plastic strain of 1×10−6 increased markedly with decreasingλ. The strain hardening rate was linear between plastic strains of 10−5 and about 5×10−3 and was independent ofλ. Basal glide was found to be the predominant deformation process during the linear strain hardening and it led to kink band formation at plastics strains of approximately 6×10−3. Probable causes of the dependence of deformation mechanics onλ are examined.
