ABSTRACT
In this chapter, the processing of biomedical alloys through cross rolling (CR), a rolling process where the strain path is changed by 90° in between two passes, is discussed. Earlier reported works indicate that CR can serve as an effective technique to obtain the desired microstructure, texture and mechanical properties, which promotes the biocompatibility of the processed material. The texture and microstructure of the alloys are influenced by both the CR and the subsequent annealing processes, which are due to the change in strain path and dynamic recrystallisation, respectively. The subsequent grain size development also affects the biodegradation properties of the alloys. In addition, the formability of the alloys is also found to have improved during CR, which makes the fabrication of small implants like stents easy. The chapter begins with a brief introduction to CR and desirable properties for various biomedical applications. An overview of various characterisations, followed by researchers to study different properties of the cross-rolled biomedical alloys, is included.
