Ultrasonic brazing of Zr-based bulk metallic glass and 1060 Al alloy using Zn-3Al filler metal

Towards the additive manufacturing of Zr-based metallic glasses using liquid phase sintering: Reactivity and phase transformation kinetics at the crystalline/amorphous interface

“…In the literature, such interactions have been reported by few diffusion bonding studies [15][16][17][18][19][20][21]. Interestingly, Zhang et al studied the joining process between a Zr-based BMG (Zr 62 Cu 33 Al 4 Ti) and a Zn alloy (3 wt% Al) around 415°C, i.e above both the glass transition temperature of the BMG (T g =410°C) and the liquidus temperature of the Zn alloy (T L =397°C) [15,16].…”

Using an ultrasound-assisted brazing method, joints with satisfactory mechanical properties (shear strength) were obtained and the growth of In the current study, the bonding mechanism will be discussed regarding both the oxide layer and possible diffusion paths in BMG.…”

Key Parameters and Optimal Design of a Split Induction Coil for T-Shaped Pipe Brazing

“…controlled in the length direction during brazing, or it will produce a force that is perpen dicular to the header pipe, thus reducing the lifetime of the brazing joint. Brazing without using furnace technologies includes mainly torch brazing [3], re sistance brazing [4], dip brazing, ultrasonic brazing [5], and induction brazing [6]. Because of its reliable control, nonnecessity of contacting the workpiece, and high flexibility, in duction brazing has a significant advantage over brazing the heat exchanger using a com plex structure.…”

“…Liu et al [18] proposed a material design strategy to simultaneously optimize multiple targeted properties o multi-component Co-based superalloys via machine learning, and a series of novel Co based superalloys was successfully selected from more than 210,000 candidates. However Brazing without using furnace technologies includes mainly torch brazing [3], resistance brazing [4], dip brazing, ultrasonic brazing [5], and induction brazing [6]. Because of its reliable control, nonnecessity of contacting the workpiece, and high flexibility, induction brazing has a significant advantage over brazing the heat exchanger using a complex structure.…”
