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.

The Quality of Welded Connections Elements from the Steel 30HGS and Titanium Alloy Ti6Al4V The aim of that work was the evaluation of the quality of welded connections elements (welds) from the 30HGS steel and titanium alloy Ti6Al4V. The metallographic, factographic tests were used, and measurements of microhardness with the Vickers method. In the head weld of the 30HGS steel there were non-metallic partial division and bubbles observed. The average microhardness in the head connection was 320 HV0.1. There was no significant increase/decrease observed of microhardness in the head influence zone of the weld. There was a good condition of head connections observed, in accordance with the standard EN12517 and EN25817. In the head weld of Ti6Al4V titanium alloy there were single, occasional non-metallic interjections and bubbles observed. There were no cracks both on the weld, and on the border of the heat influence zone. The value of microhardness in head connection was in the range 300÷445 HV0.1. Reveal a very good condition of the head connections in accordance with the standard EN12517 and EN25817. The factographic tests prove the correctness of welded connections done and then heat treatment in case of steel and titanium alloy.

The paper presents the affect of temperature and time of annealing on the thickness of the obtained oxide layer on the surface of titanium alloy Ti6Al4V and also on the geometry of the layer. The studies on seven samples where they were determined from 1 to 7 were carried out. Sample 1 was a reference sample of material that was subjected to the following parameters: for the sample 2 the temperature 350 �C in 5 hours, for the samples 3 and 4 450 �C and in sequence 1 and 10 hours, for the sample 5 and 6 550 �C and in sequence 1 and 10 hours and for the sample 7 temperature 650 �C in 5 hours. Studies have shown that thicker oxide layers with less surface development form on samples occurred after longer heat treatment and higher temperatures. Thanks to these dependencies it is possible to maneuver the time and temperature of the treatment interchangeably, eg. by raising the temperature of annealing time can be shortened to obtain similar parameters of the roughness profile as for the sample processed at a lower temperature in a longer time.

Single-grain grinding test plays an important part in studying the high speed grinding mechanism of materials. In this paper, a new method and experiment system for high speed grinding test with single CBN grain are presented. In order to study the high speed grinding mechanism of TC4 alloy, the chips and grooves were obtained under different wheel speed and corresponding maximum undeformed chip thickness. Results showed that the effects of wheel speed and chip thickness on chip formation become obvious. The chips were characterized by crack and segment band feature like the cutting segmented chips of titanium alloy Ti6Al4V.
