Abstract This article introduces the different types, distinctions, and grades of commercially pure titanium and titanium alloys. It describes three types of alloying elements: alpha stabilizers, beta stabilizers, and neutral additions. The article discusses the basic categories of titanium alloys, namely, alpha and near-alpha titanium alloys, beta and near-beta titanium alloys, and alpha-beta titanium alloys. It also describes the general microstructural features of titanium alloys.

The aerospace industry is undergoing tremendous changes causing a shift in focus, methodology, and the speed of innovation. The "NewSpace" sector of the aerospace industry consists of almost 1,000 companies focused on creating different business models for accessing space. As a result, the role of The Aerospace Corporation (Aerospace) as a trusted advisor on space programs is taking on a new focus as our customers are working directly with the NewSpace sector. The speed and agility of NewSpace and an increasing focus on space security is pushing Aerospace to elevate our culture of innovation. In this paper, we describe the programs we created to stimulate this culture and engage our employees in more innovative practices.

Abstract : This represents a second edition of an earlier handbook bearing the same title and the designation SST 65-8, dated August, 1965. The handbook represents a collection of data from many sources on the properties and fabrication characteristics of commercially pure titanium and eight titanium alloys including Ti-5Al-2.5Sn, Ti-8Al-1Mo-1V, Ti-6Al-4V, Ti-6Al-6V-2SN, Ti-13V- 11Cr-3Al, Ti-4Al-3Mo-1V, Ti-2.25Al-11Sn-5Zr-1Mo-0.2Si and Ti-6Al-2Sn-4Zr-2Mo. Section 1 describes the metallurgical characteristics of titanium and these alloys. Sections 2, 3, and 4 concern themselves with the availability of mill products, machining, and joining technology, respectively. Section 5 treats the subject of mechanical properties for these materials in a manner patterned after MIL-Handbook 5.

Titanium alloys are highly adaptive to the manufacture of military, aircraft and medical devices due to their high tensile strength and toughness. However, the traditional processing path of titanium alloys are difficult and costly, which restricted the wide applications of titanium alloys. Additive manufacture has provided new processing routings for titanium alloys, with which high qualified components can be produced efficiently. Selective laser melting and laser metal deposition are two frequently used processing routings for additive manufacture of titanium alloys; while the former is powder bed based and can be used to produce fine components, the latter is powder feeding based and can be utilised to produce large components. With different forming mechanisms, the processing routings exhibit different characteristics in forming capacities, surface roughness, inner microstructures and mechanical properties, during their applications on titanium alloys. The development, characteristics and the applications of these two techniques in titanium alloys are reviewed, and the future developments of laser additive manufacture of titanium alloys are also discussed.

This paper presents the current development and formulate the future direction of selective laser melting (SLM) technology in the aerospace industry. The potential application and challenges of SLM in producing aerospace industry components, their key requirements, and the mechanical properties of the built parts were discussed. SLM technology can be considered a viable method in the aerospace industry when all process parameters are controlled, consistent and the printing process is stable. This paper fulfills a need to evaluate the SLM technology in terms of application in the aerospace industry, as there are no viable studies that directly address this issue.
