This article reviews the mechanisms, types, and causes of cracks in nickel-based superalloys fabricated by Selective Laser Melting. Due to low thermal conductivity, wide solidification range, and severe shrinkage, SLMed superalloys are prone to solidification cracking, liquation cracking, DDC, and SAC. These defects arise from interdendritic segregation, liquid-film rupture, grain-boundary sliding, γ′ coarsening, and rafting. Although powder design, optimized scanning strategies, and heat treatment can reduce cracking, challenges remain. Future research must focus on process optimization, new alloy formulations, and improved post-processing to enhance the reliability of SLM-produced nickel-based superalloy components.
As manufacturing demands quickly evolve in 2025, many businesses are discovering that investing in laser cutting and engraving equipment isn’t just a trend — it’s a strategic move for growth. Below is a real-world case study + market insight analysis that illustrate why more companies are adopting l
As the holiday season arrives, demand for personalized gifts, high-quality decorations, and fast-turnaround production has reached its yearly peak. This Christmas, more factories, workshops, and creative studios are turning to laser engraving and cutting machines to keep up with seasonal orders and
