Research Highlights

3D view of layered wide-gap brazement, post-infiltration, held for 60-minutes at 1205°C and b) isolated porosity revealed within the layered wide-gap brazement.

Cross-sectional view of braze infiltration into the MAR-M247 skeleton at various points: a) MAR-M247 skeleton, b) 1068°C, c) 1130°C and d) 1150°C; Red indicates “un-infiltrated” regions, whilst purple indicates “infiltrated” regions.

Resultant microstructure of a layered wide gap brazement brazed at 1205°C + 60-minute hold, revealing large 𝛾-Ni matrix grains, with athermally solidified eutectic constituents along the grain boundaries and junctions.

To observe the insitu agglomeration of the inclusions, experimental technique is established using HT-CSLM (High-temperature Confocal Scanning Laser Microscopy). We can calculate the attractive capillary forces existing between the inclusions.

A new model was developed in-house at McMaster University for simulating ladle refining reactions in Si-Mn killed steel considering the different reactions between steel, slag, and inclusions.
