The mechanical properties and fracture failure behavior of the near β-type Ti-5Al-5Mo-5V-3Cr-X (X = 1Fe or 1Zr) titanium alloys were studied by Split Hopkinson Pressure Bar (SHPB) experiment under the dynamic loading conditions at a strain rate of 1.5 × 103 s-1–5.0 × 103 s-1. Results showed that the SHPB specimen fractured in the direction of maximum shearing stress at an angle of 45° with the compression axis. The fracture surface revealed the shear and tension zones with cleavage steps and parabolic dimples. Severe early unloading was observed on the Ti-5553 alloy under a strain rate of 4,900 s-1 loading condition, and the dynamic property of the Ti-55531Zr alloy was proved to be the optimal.

Strength And Ductility

CP-Ti, Ti 6A l 4V (ELI), and Ti 6Al 7Nb are often used for manufacturing osteosynthesis products or implants. However, researches have revealed that Al and V can have detrimental effects on the human body. Therefore, several Al- and V-free near-α and (α+β) titanium alloys have been developed on the basis of CP-Ti Grade 4+ (Ti 0.4O 0.5Fe 0.08C). They should possess similar or better mechanical properties than Ti 6Al 4V (ELI) combined with an improved biocompatibility and good corrosion resistance. O, C, Fe, Au, Si, Nb, or Mo have been used as alloying elements, which are either already present in the human body or are biocompatible. Several of the studied alloys show a strength and ductility fulfilling the requirements of Ti 6Al 4V ELI as specified in ASTM F136. For instance, Ti 0.44O 0.5Fe 0.08C 2.0Mo exhibits a YTS of approx. 1005 MPa, an UTS of approx. 1015 MPa, and an elongation at rupture of at least 17%. Therefore, one or more of the studied alloys are promising candidates for replacing Ti 6Al 4V ELI in osteosynthesis and implant applications.

Strength And Ductility

Abstract The temperature and strain rate effects on the shear properties of selected Pb-free solders were investigated. The experiments were performed using single lap shear specimens. All testing was performed using a standard tensile test metrology. The following results were found: 1) Sn-3.5 wt.% Ag outperformed all the other solders in terms of its mechanical strength at all test conditions due to the formation of Ag3Sn precipitates in the bulk solder and Cu6Sn5 intermetallic formation along the interface. However, ductility was sacrificed as this solder strain hardens. 2) The strength and ductility of the solder joint is strongly dependent on the test temperature and strain rate. Data in this work reflects a decrease in strength and ductility when the test temperature is increased. This phenomenon can be attributed to the increase in energy as temperature is increased to overcome dislocation barriers such as impurities and grain boundaries that impede the motion of dislocation. When strain rate is increased, the amount of plastic deformation experienced by the solder increases and more dislocations are formed. Due to the increase in proximity and number of the dislocations, the net result is that motion of the dislocations are hindered thus requiring more stress to deform the material.

Strength And Ductility

The high strain rate tensile properties of solution annealed Type 304 stainless steel have been determined experimentally. Tests were performed at strain rates ranging from 3 × 10−5 to 1 × 102 in./in./sec at temperatures from 600 to 1600 deg F. At temperatures to 1000 deg F, the strength and ductility are largely insensitive to variations in strain rate, whereas at temperatures from 1200 to 1600 deg F, significant increases in both strength and ductility are observed with increasing strain rate.
