Titanium Alloy Ti6al4v

As a typical high specific strength and corrosion-resistant alloy, titanium alloy Ti6Al4V is widely used in the aviation, ocean, biomedical, sport, and other fields. The heat treatment method is often used to improve the material mechanical properties. To investigate the dynamic mechanical properties of titanium alloy Ti6Al4V after heat treatment, dynamic compressive experiments under high temperature and high strain rate were carried out using split Hopkinson press bar (SHPB) equipment. The stress–strain curves of Ti6Al4V alloy under different temperatures and strain rates were obtained through SHPB compressive tests. The Johnson–Cook (J–C) constitutive equation was used for expressing the stress–strain relationship of titanium alloy under large deformation. In addition, the material constants of the J–C model were fitted based on the experimental data. An orthogonal cutting simulation was performed to investigate the cutting of Ti6Al4V alloy under two different numerical calculation methods based on the established J–C model using the finite element method (FEM). The simulation results confirm that the adiabatic mode is more suitable to analyze the cutting of Ti6Al4V alloy.

Remarkable Agreement

Vibration modes and damping behaviour of a Portland cement-based, fibre-reinforced composite, were evaluated experimentally and the results compared to computer simulations performed based on the measured properties of the composite. The remarkable agreement between simulation and experiment demonstrates the feasibility of producing Hi-Tech cement-based materials for non-conventional applications.

PB-1/PP blend was prepared by blending isotactic polybutene-1 and polypropylene with the ratio of 80/20 through Brabender extruder under melted condition, injected into the standard samples. After heat treatment at 75°C, the crystallization, crystal forms, dynamic mechanical properties, mechanical properties of the blends were studied via differential scanning calorimetry (DSC), X-ray Diffraction (XRD), dynamic mechanical analyzer (DMA) and mechanical testing machines, respectively. It was found that after heat treatment: both the melt temperature and the melting enthalpy of crystal form I in PB-1 component increased, the melt peak of crystal form II decreased gradually, while the melt temperature and melting enthalpy of PP as a disperse phase, maintained unchanged basically; the storage modulus of the blend increased and the tan δ decreased a bit; the mechanical properties of the blend were improved noticeable.
