Following the fabrication of TC4 titanium alloy components using Selective Laser Melting (SLM) technology, metallographic analysis serves as the core method for evaluating internal quality and performance potential.

FeCrAl alloy is a high-performance electrothermal alloy widely used in industry, featuring outstanding advantages such as high electrical resistivity, excellent high-temperature resistance, strong oxidation resistance, and long service life. It maintains stable microstructure under high-temperature operating conditions and is resistant to deformation and failure. It is extensively applied in industrial electric furnace heating elements, household appliance heating elements, high-temperature kilns, heat treatment equipment, and aerospace high-temperature heating components — making it an indispensable key material in high-temperature electrothermal and heat-resistant structural applications.

EBSD (Electron Backscatter Diffraction) is the "microscopic lens" for alloy steel R&D and quality control! It precisely captures core information such as grain orientation, grain boundary characteristics, phase distribution, and dislocation density, revealing the correlation between microstructure and strength, toughness, and corrosion resistance. It provides direct evidence for optimizing rolling and heat treatment processes, and identifying failure risks — making it an essential tool for transitioning from "empirical development" to "precision control."

A magnetic core (Magnetic Core) is a magnetic component made of ferromagnetic materials (such as iron, silicon steel, ferrite, etc.). Its main function is to concentrate and guide the magnetic field. It is an indispensable core component in many electronic and electrical devices.
