microstructure in copper and its stability during heat treatments, and also to compare test results of uniaxial compression and tension properties at room temperature, with the response based on the interaction of dislocation anticipated from calculations . The mechanical properties and microstructure of the nanostructures and ultra-fine-grained Effect of Microwave-Activated Sintering on Microstructure Apr 23, 2021 · When the graphite/copper composite is used as an electronic packaging material, it is difficult to take advantage of the thermal conductivity due to its poor interface bonding. In this study, rapid microwave sintering was used to improve the properties of composites, and the wettability between graphite and copper was improved by adding titanium. The results show that microwave sintering can
Nov 07, 2016 · Abstract. The purpose of this article is to study the effect of heat treatment on the interfacial microstructure and properties of the Cu-Al contact reaction brazed joint, and compare the results with a similar study performed on flash welding. The results show that the interfacial intermetallics in Cu-Al joint change from original two layers (Cu 9 Al 4 /CuAl 2) to three layers (Cu 9 Al Effects of copper content on the microstructure and Dec 09, 2015 · The microstructure, phase constitution, melting character, and 6061 aluminum alloy brazing properties of Al-Si-Cu-Zn-Re filler metals with different copper contents were investigated. The Al-9.6Si-10Cu-10Zn-0.1Re, Al-9Si-15Cu-10Zn-0.1Re, and Al-8.4Si-20Cu-10Zn-0.1Re filler metals had the same solidus, at about 502 °C. Increasing the copper content lowered the liquidus temperature of the
Ti3SiC2 ceramic and copper were successfully vacuum brazed using Ag-Cu-Ti filler and Ag-Cu-Ti filler with copper mesh, respectively. In this study, the effects of copper mesh and brazing parameters on the interface microstructure and mechanical properties of the joints were systematically studied. The results revealed that the typical interfacial microstructure of joint was Ti3SiC2 ceramic Interface Microstructure and Mechanical Properties of The composite was produced by pouring melt Al into solid Cu pipe. Microstructure, mechanical properties and Cu-Al composition distribution in Cu/Al composite interface were studied in the paper. The experimental results show that Cu and Al diffuse to each other, which the Cu/Al interface zone is formed. Moreover, there are lots of Cu-Al phase appearing in the Cu/Al interface zone.
In the present study, copper was used as an intermediate material in diffusion bonding between titanium and stainless steel. The process was carried out in the temperature range of 850 °C to 1000 °C for 60 minutes and at 900 °C for 30 to 150 minutes under the compressive stress of 3 MPa in a vacuum. The effects of temperature and time on the microstructure of Ti Cu stainless steel Interface microstructure and mechanical properties of Relatively the high reflectivity of copper to CO <SUB>2</SUB> laser led to the difficulty in joining copper to steel using laser welding. In this paper, a new method was proposed to complete the copper-steel laser butt welding. The scarf joint geometry was used, i.e., the sides of the copper and steel were in obtuse and acute angles, respectively. During the welding process, the laser beam was

Electromagnetic pulse welding can be categorised as a fast, precise, and contactless solid-state joining process. When applied to aluminium and copper, electromagnetic pulse welding opens the possibility of entirely suppressing, or at least minimising, the intermetallic phases of cracking susceptible microstructures.
