Introduction

Comparative analysis of core detection methods

Comparison dimension	Microscope method	Industrial CT method
Detection principle	Cross-section metallographic analysis	3D penetration reconstruction
Resolution limit	5μm pore detection	10μm pore detection
Image dimension	2D cross section Unidirectional observation in normal direction	3D stereo Omnidirectional observation
Sample loss	Mounting consumables	Non-destructive testing

Substantial technological breakthrough

Based on the statistics of 107K full particle size data, the literature shows that the resolution of titanium alloy powder detection has reached the precise magnitude division: 38μm+5% error band verifies the scientific boundary of the standard
