Characterization, shear strength and corrosion resistance of self joining AISI 304 using a Ni Fe–Cr–Si metallic glass foil

Induction Brazing of 304 Stainless Steel with a Metalloid-Free Ni-Zr-Ti-Al-Sn Amorphous Foil

“…Besides, the avoidance of borides and silicides due to the adoption of metalloid-free ller metal may be another reason for the high shear strength of the joint. The shear strength is higher than the maximum average shear strength value of 108 MPa obtained by adopting MBF Metglas ® Ni 76.5 Fe 4.2 Cr 13 Si 4.5 for 304 SS brazing 10) .…”

“…[1][2][3][4][5][6][7][8] . These ller metals can be applied in forms of powders, powder-based pastes, rolled plates or tapes, or Metglas ® amorphous brazing foils (designated as MBF) [8][9][10][11][12][13][14] . The amorphous brazing foils made by rapid solidi cation have been used predominantly due to many advantages such as the amorphous structure with uniform composition and homogeneous phase state, a narrow temperature interval of melting point, a short brazing time and high atom diffusion rate 9,15,16) , thus homogeneous brazing joints can be obtained.…”

Fabrication and Evaluation of Hybrid Components of Wc/Inconel 600 by Liquid State Diffusion Bonding

“…The specimens to be joined were placed in a graphite die embedded in a boron nitride (99.5% pure) powder bed; this die consists of a screw that on turning clockwise can impart pressure to the sandwich assembly in order to prevent movements of the pieces by keeping the joints in contact. The experimental apparatus use to join the sample combinations as been describe elsewhere [22], and consists of a resistance furnace with alumina-tube chamber of 80cm long and 8cm in diameter. Joining experiments were carried out on WC/Cu-Zn/Inconel 600 combinations at temperature of 980°C and 1000°C using different holding times in Ar.…”

Image Processing-Based Analysis of Temperature Dependent Interlayer in Brazed Fe-Cr-Al Alloy (Fecralloy®) with Ni-Based Filler Metal

“…The acquired images showed the intensities of the constituent of materials across the bonding layers, and they were used to investigate bonding qualities. However, the research to quantify the penetration depth of materials in the bonding process by analyzing the change of the border line of filler metal and the distribution of newly formed phase distribution has been rare even though they are important factors to determine the bonding characteristic and quality [19,24]. In addition, there have been few attempts to analyze the Cr x B y and Ni x Al y phases that determine the bonding quality by quantifying the distribution of materials using image processing of SEM-EDS images.…”
