FLT cracks, also known as fault line cracks or fractures, are openings or fissures in the Earth's surface that occur along fault lines. These cracks can be small or large, depending on the tectonic forces acting on the fault line. FLT cracks can be caused by a variety of factors, including:
The formation of hot cracks is driven by a combination of material properties, metallurgical impurities, and mechanical stresses. 1. Low-Melting-Point Impurities flt cracks hot
As a casting cools, it naturally shrinks. If the mold design is too rigid (low collapsibility), it resists this natural contraction. This resistance creates mechanical tensile stress across the solidifying zones, pulling the weak dendritic structures apart. 3. Poor Liquid Metal Feeding FLT cracks, also known as fault line cracks
