Feb 22, 2016 · Micro-additions of Cr, Zr, Ti, and V positively affected the Al-Si-Cu-Mg alloy strength. The modified alloy in the T6 temper condition during uniaxial tensile tests exhibited yield strength of 289 MPa and ultimate tensile strength of 342 MPa, significantly higher than that for the Al-Si-Cu-Mg base alloy. Effect of Cr, Ti, V, and Zr Micro-additions on Feb 22, 2016 · Uniaxial static and cyclic tests were used to assess the role of Cr, Ti, V, and Zr additions on properties of the Al-7Si-1Cu-0.5Mg (wt pct) alloy in as-cast and T6 heat-treated conditions. The microstructure of the as-cast alloy consisted of -Al, eutectic Si, and Cu-, Mg-, and Fe-rich phases Al2.1Cu, Al8.5Si2.4Cu, Al5.2CuMg4Si5.1, and Al14Si7.1FeMg3.3.

Influence of pulse frequency on microstructure and

Jan 15, 2021 · Abstract. As an important parameter of HIPIMS, pulse frequency has significant influence on the microstructure and mechanical properties of the deposited coatings, especially for the multi-component coatings deposited by using a spliced target with different metal sputtering yields. In this study, a single Al 67 Ti 33 -V-Cu spliced target was designed to prepare Al-Ti-V-Cu-N coatings by Liquation and Crystallization Cracks in Aluminum Alloy In this work we studied the microstructure and microhardness of standard AA2024 alloy and AA2024 alloy with the addition of 1.5% Y after pulsed laser melting (PLM) and selective laser melting (SLM). The SLM process was carried out with a 300 W power and 0.1 m/s laser scanning speed. A dispersed microstructure without the formation of crystallization cracks and low liquation of alloying Microstructure and Mechanical Properties of Cu Matrix The CTBN particles were found to be in a special core-shell structure with a Cu-Ti alloy core and a TiB 2 /TiN ceramic shell. The test results presented obvious improvements in mechanical properties. The highest ultimate tensile strength reached up to 297 MPa, 77 MPa higher than that of Cu.
