Structure, Texture and Tensile Properties of Ti6Al4V Produced by Selective Laser Melting

Abstract

Additive manufacturing has recently expanded its potential with the development of selective laser melting (SLM) of metallic powders. This study investigates the relation between the mechanical properties and the microstructure of Ti6Al4V alloy produced by SLM followed by a hot isostatic pressing (HIP) treatment. HIP treatment minimizes the detrimental influence of material defects. Tensile specimens produced with reference to specific building axes were prepared using a Renishaw A250 system. It has been found that the tensile strength and elongation depend on specimen building direction. Microstructural and textural characterizations were carried out to identify the source of differences.

Effects of Process Cutting Parameters on the Ti-6Al-4V Turning with Monolithic Driven Rotary Tool

“…Titanium is an important construction metal developed in the 1950s. Titanium alloys are widely used in a variety of fields due to their high strength, corrosion resistance, and heat resistance [ 26 , 27 ]. Although titanium is heavier than aluminum, it is also stronger in terms of specific weight.…”

Morphological analysis of plasma electrolytic oxidation coatings formed on Ti6Al4V alloys manufactured by electron beam powder bed fusion

“…On the flip side, Ti6Al4V, the most widely used titanium alloy, finds common application in the biomedical and healthcare fields owing to its high corrosion resistance, mechanical strength, low density, and biocompatibility [ [5] , [6] , [7] , [8] , [9] ]. The additive manufacturing of Ti6Al4V alloys has gained significant attention, particularly over the past two decades [ [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] ]. For said manufacturing, powder bed fusion methods using laser (PBF-L) and an electron beam (PBF-EB) are the most generally accepted technologies.…”

QUality CONTROL BASE ON surface roughness CHARACTERISTIC – OXIDE layer on PURE titanium

“…Titanium and its alloys are a group of metallic materials that enjoy the greatest interest in medicine, especially in implantology [1,2]. Titanium owes this special distinction to the medical industry: relatively low specific gravity (density), very satisfactory ratio of strength to density or yield strength, very good strength in fatigue tests, among metallic biomaterials the lowest value of Young's modulus, but most importantly biotolerance, tendency to spontaneous passivation, high local and general corrosion resistance [3][4][5][6][7]. Intensive development of the industry (especially medical industry), the search for new solutions, an effort to implement the principles of Industry 4.0 and sustainable development [8,9], invariably based on the proper and thorough knowledge of mechanisms occurring spontaneously (or without human ingerention) -often such processes are called special processes, of which the assessment quality is particularly difficult and requires the use of destructive testing and statistical analysis [10].…”
