This work addresses the challenges in brazing thermohydraulic sealings involving dissimilar materials, specifically 316Ti stainless steel and alumina, which have significantly different coefficients of thermal expansion (CTEs) and elastic constants. Traditional brazing methods require complex interlayers or extensive metallization steps, leading to issues such as dimensional changes, braze voids, and inadequate corrosion resistance due to prolonged high-temperature exposure.

Ceramic-on-ceramic joints are notorious for their inherent brittleness, posing challenges for high-performance applications. To address this, a novel approach is proposed to enhance the involvement of filler metals during fracture. This study investigates the controlled initiation and propagation of cracks in Al2O3–Al2O3 joints through a strategic combination of laser pre-cracking, laser patterning, and laser active brazing techniques.

UK university staff have threatened to extend strikes that have impacted thousands of students. Representatives from the University and College Union (UCU) said the action would continue following an unsuccessful meeting with employers on Monday and that they were considering asking their members to extend the strike mandate. The union announced more strike days and said it would continue its marking boycott, which has disrupted graduations and left many students without their final grades.
