A Review Paper Powder Metallurgy Process on Ti-6al-4v Combine with Metal Injection Moulding

Metal Injection Moulding (MIM) of Ti-6Al-4V is an advanced manufacturing technique aimed at producing complex titanium alloy parts with high precision, minimal waste, and reduced costs. Ti-6Al-4V, a titanium alloy known for its excellent strength-to-weight ratio, corrosion resistance, and biocompatibility, is extensively used in aerospace, biomedical, and automotive applications. However, traditional methods for shaping titanium are costly and time-intensive. MIM offers a solution by combining the design flexibility of plastic injection moulding with the strength of metal alloys. This process involves mixing fine Ti-6Al-4V powder with a binder, injecting it into a mould, and subsequently debinding and sintering the part to achieve full density. Critical parameters, such as powder size, binder composition, sintering temperature, and atmosphere, play a crucial role in determining the mechanical properties and surface quality of the finished product. The study focuses on optimizing these parameters to minimize defects and achieve desired properties, making MIM a viable, cost-effective alternative for producing high-quality titanium alloy components. Results indicate that MIM can produce Ti-6Al-4V parts with mechanical properties comparable to those of traditionally manufactured components, supporting its potential for broader application across industries.
