The minor modifications in the alloying elements affect the wetting and spreading behavior and should be designed according to the type of the Ti parent metal. For instance, comparing the fillers Al-4.5Mg-0.4Si-0.1Cr and Al-4Mg0.5Si-0.4Mn [30], the former with more 0.5%Mg and 0.1Cr instead of 0.4Mn, has a lower contact angle and better spreading on Grade 5 titanium; by contrast, these modifications have a different effect in brazing Grade 2 titanium.
HCP deposits can tolerate temperatures as low as -70[degrees]F up to 800[degrees]F and withstand pressure of up to 30,000psi, depending on the parent metal and the operating conditions.
[5] increased the tensile strength 70% higher than that of the parent metal in Al-TiB2 composite fabricated by FSP.Farzad Heirani et al.
Since the 3 temperatures are important in SFRs, namely, shutdown temperature (200[degrees]C), normal operating temperature (400[degrees]C), and peak temperature (550[degrees]C), the tensile tests were carried out at those temperatures for the parent metal and welded samples separately and the results were compared.
The cracks propagate through the thickness of the weld bead and stop at the parent metal, as long as it's not brittle.
These factors, along with 2.5 times greater application velocity, reportedly results in a stronger bond with the parent metal of the screw and improved wear resistance.
Purchasing pre-alloyed ingot stock with the percent reinforcement desired and metallurgical bond between the parent metal and particles is recommended.
Heat treatment of pipe welds is necessary to match the properties of the pipe parent metal and the weld.
The installed system also utilises sophisticated software to facilitate stitching of multiple images, accommodating the microscopic assessments of complete welds, heat affected zones and parent metal. The machine test specimen stage is capable of achieving indentation spacing of just 250 pm in conjunction with a 1kgf hardness force producing arrays of over 6,000 hardness points.
For example, in 6XXX series, the welding heat can reduce the strength of the parent metal by half.
