Mechanical Properties And Corrosion

Abstract Ti-6Al-4V components were developed in different orientations (horizontal and vertical) using an additive manufacturing technique called direct metal laser sintering and heat treated under three different procedures. Anodizing (18- 22 V) the vertically built heat treated-2 specimen yields an optimum combination of mechanical properties and corrosion resistance tested in an acidic environment. The anodized (18- 22 V) heat treated-1 specimen built in horizontal orientation performed better in terms of combined mechanical properties and corrosion resistance tested in ringer solution.

Microstructures And Mechanical Properties

The microstructural evolution and mechanical properties of as cast AZ91 Mg alloy enduring different homogenization conditions were researched. The results show that the peak stress and plasticity obtain improvement with the increase of heat treated time and temperature until 693K. When the temperature is higher than 743K, the sample will occur the over-burned and directly lead to the decrease of mechanical properties. Otherwise, with the increase of heat treated time and temperatures, the second phase gradually precipitate from the solution, while the grain evolution is not obvious. In the compression process for the samples after heat treatment, some twins could be found in the grains.

Cp Ti

Titanium and its alloys used in biomaterial applications are preferrably the cause of high-corrosion resistance properties in addition to having good mechanical properties. Commercially pure Ti (CP-Ti) (Grade 2), Ti6Al4V (Grade 5) and Ti6Al4V-ELI (Grade 23) samples are used as biomaterials exposed to 750°C and 1060°C for 1[Formula: see text]h. The samples were cooled in air after heat treatment at 750°C, the other samples were cooled in water after heat treatment at 1060°C. The free-heat treatment samples are as producted. Microstructures of heat-treated samples and non-made samples by comparison were evaluated before and after corrosion process microstructures and tensile strengths. Test solution is 0.5[Formula: see text]mol H2SO[Formula: see text][Formula: see text]mol HCl mixture. The corrosion resistance of the titanium samples was evaluated. Microstructure images were monitorized on optical and SEM microscopes. In this paper, the effect of heat treatment was determined on the microstructure, mechanical properties and corrosion resistances of the material. As a result, heat treatment is useful on corrosion resistance of alloyed samples.

Mechanical Properties And Corrosion

In the present work, the effect of Cr and Mn addition on corrosion resistance was investigated on AlSi3Mg alloy. Potentiondynamic corrosion tests in a 3.5 wt. % NaCl solution were performed on samples in different heat-treated conditions, and corrosion current density and potential were determined by Tafel method. Brinnel hardness measurements were also carried out in order to couple corrosion resistance with mechanical properties. It was interestingly found that Cr presence enhanced mechanical properties and corrosion resistance in comparison with the base alloy.

Mechanical Properties And Corrosion

In this paper, the samples were heat treated by two-stage artificial aging to investigate the effect on the mechanical properties of the 7150-T77 aluminum alloy, and finally subjected eventually to the ESCO corrosion test according to ASTM G34-01 standard. The results have shown that the mechanical properties and corrosion resistance induced by cracking at alloy 7150 can be improved by two-stage customized heat treatment for a specific application in the aeronautical industry.
