Powder metallurgy (P/M) offers opportunity in making net shaped parts with competitive cost and strength for parts produced by stamping, machining, casting or forging. The versatility of this material shaping technology and its unique capabilities in fabricating extremely high performance and complex shaped components has developed over the past few decades. In particular, net-shaping process such as micro-powder injection molding is being explored as the optimal PM net-shaping technology for fabricating complex type PM micro-components. However, such net-shaping technology requires more critical processes to achieve shrinkage uniformity and sound microstructure with deceasing size of a part. To overcome these issues, great efforts have been paid to design optimal feedstock using fine powders including nanoscale powders. However, there are some restrictions to the usage of of fine powders because of the difficulties in entire PM processes from mixing, shaping to full-density sintering.
In this special issue, novel trends related to processing as net-shaping and consolidation, and powder material design suitable for the production of advanced net-shaped PM parts as well as related properties are highlighted and discussed.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed Open Access monthly journal published by MDPI.
