ABSTRACT
This chapter aims to assess the impact of hot isostatic pressing (HIP) on the high-cycle fatigue life of Ti-64, stress-life plots were developed to compare the fatigue life of HIP-treated specimens with that of a stress-relieved baseline. Experimental research was conducted on the fatigue life of selective laser melted Ti-6Al-4V. A thorough understanding of the fatigue life performance for additively manufactured parts is necessary before such parts are utilized as production end-items for real-world applications such as the rapid, on demand, and 3D printing of aircraft replacement parts. Layer-based additive manufacturing (AM) technology, commonly known as 3D printing, is widely utilized as a cost-effective method for rapid prototyping with polymer-based materials. The availability of high-strength metals and machines capable of precision 3D manufacturing provides opportunities for the rapid manufacturing of end-use parts for a wide array of applications. Several metal-capable 3D-printing machines have been developed and marketed for commercial use.
