In this paper, the impact fatigue test of TC18 titanium alloy was carried out on the Instron 9350 drop hammer impact testing machine (Fig. 1) by a self-designed fixture (Fig. 2 and Fig. 3) and specimens (Fig. 4). The impact energy range of the testing machine is between 0.59 and 1800 J, and the simulated impact velocity range is 0.75 ∼ 24 m/s. With the advent of advanced testing techniques such as laser-induced particle impact test, it is possible to study materials mechanics under extremely high deformation rates, i.e., above 10 6 s −1, a relatively less explored regime of strain rates.Inspired by the classical Taylor impact test, in this study, we accelerate microparticles of commercially pure titanium .

Common Elements Alloyed with Titanium. Here are some of the common alloy elements and their effects: Aluminum (Ti-6Al-4V): Thanks to its superb combination of high strength and anti-corrosion properties of Ti-6Al-4V, often employed in aerospace, marine and medical sectors. Vanadium (Ti-6Al-4V): Vanadium is an important additive for titanium, as it . To study the impact fatigue properties of TC18 titanium alloy and propose a new damage model for the impact fatigue life prediction of material, the impact fatigue test method and the impact response measurement scheme are designed. The impact fatigue tests are then implemented on a drop hammer impact test machine to obtain the fatigue lives and impact . Another important aspect that lacks significant understanding is crack propagation behaviour of titanium and titanium alloys during impact toughness testing. There are several studies that investigated the fracture surfaces of Ti-6Al-4V alloy after impact testing [1,4,5,6,8,9]. However, there were only a limited number of studies that .
Conclusions Based on two series test, the ballistic impact mecha- nism and failure modes of titanium alloy TC4 have been investigated and the ballistic limit equation is verified by test results. Within the limited tests, the conclusions can be drawn as follows: 1) On the impact, the main damage of flat and subscale casings are similar.
Zac does confirm that the outer frame of the iPhone 15 Pro series is indeed Titanium and of high quality. The display performs very well in the flame test, but surprisingly, the iPhone 15 Pro Max .The response of direct metal laser sintering (DMLS) produced Ti6Al4V (ELI) to impact was investigated using an instrumented Charpy impact test machine and V-notch specimens.
As boundaries in titanium alloys with mechanical property discontinuity, i.e., phase or grain boundaries, are highly apt to initiate cracks [23], morphology of the main constituent phases (i.e., the HCP α phase and the BCC β phase) is crucial to the toughness of titanium alloys.As stated above, it has long been established that a coarse lamellar structure is more .

The test methodology . Thanks to high speed cameras fixed underneath the cars during testing, we have a close-up view of what happens to the objects on impact. As illustrated in the slow motion videos below, the shields destroy everything from a solid concrete block to a steel alternator and safely capture and eject objects made of ultra-hard steel.In this paper, Charpy notched pendulum test was used to study the impact properties of Ti6211 titanium alloy at -60 ℃, -40 ℃, -20 ℃, 23 ℃, 100 ℃, 200 ℃ and 300 ℃, respectively, and the fracture morphology was analyzed. The ductile and brittle transition temperature of the material was deduced from the area of the radiation zone.

AbstractBallistic impact testing was conducted on aluminum (Al) 2024 and titanium (Ti) 6Al-4Vanadium (V) sheet and plate samples of different thicknesses. The tests were conducted on flat panels with two different areal dimensions: 61×61 cm (24×24 in.) (large panel) and 38×38 cm (. Titanium alloys with twinning- and transformation-induced plasticity effects display promising mechanical properties, particularly, high impact toughness, unlike conventional titanium alloys.
