Chapter 3. Typical Materials for Electron Beam Wire Deposition
Abstract
This chapter mainly deals with the issues concerning materials used in EBWD technology. A brief introduction on the present status of materials used for EBWD investigations was given at the beginning of this chapter. Following that, characteristics, technical requirements and manufacturing methods of feeding wires used for EBWD technology are proposed and discussed. After that, the main technical features of typical EBWD deposits, namely burn loss of alloying elements, anisotropy of mechanical properties, macrostructure characterized by columnar crystals and “three zones and two lines”, are introduced separately in different sections. For the aim of properly matching the different mechanical properties of EBWD parts, researching results on effects of alloying element content, depositing beam current and heat treatment schedules on microstructure and mechanical properties of EBWD Ti–6Al–4V deposits are introduced and discussed. Based on which, methods for tailoring of mechanical properties of EBWD products similar to Ti–6Al–4V alloy are proposed. Near the end of this chapter, new findings on fracture modes and deformation mechanism in tensile tests of EBWD Ti–6Al–4V are illustrated. In the end of this chapter, several materials developed and certified to be suitable for EBWD use are introduced and typical mechanical properties of their EBWD deposits are listed. The primary intention of the present chapter is to give a preliminary understanding of the EBWD technology and its typical products for the beginners and potential users interested in this technical field.
