Description

This text provides an authoritative guide about basics of feedstock technology, the latest developments in binders for titanium metal injection moulding and their potential implications keeping in mind the broader view of research and commercialization. It also presents challenges that MIM technology of reactive metals is currently facing and the potential solutions for commercial success.

Both commercial growth and research development are fundamentally driven by the economics of manufacture. By presenting the problems and their potential solutions in the case of reactive metals MIM, this text provides a valuable resource for engineers intending to utilise MIM in commercial products design.

Key Features

  • Provides comprehensive details and case studies on the feedstocks currently under extensive development, in research and commercial domain
  • Discusses the most recent development of the binder chemistry and design, the most critical challenges in MIM technology
  • Includes comprehensive evaluations with regard to feedstock characterisation and impurity control

Readership

Researchers and engineers working in materials science. Graduate students and researchers in metallurgy and light alloys. Researchers and engineers in titanium industry
