Abstract

Titanium alloy powder metallurgy products are widely used in aerospace, medical and bioengineering fields because of their excellent mechanical properties and biocompatibility. However, the defects in the metallurgical process are recognized as one of the constraints. The aim of this study is to analyze and solve the common defects in titanium alloy powder metallurgy products, such as holes, inclusions, cracking and so on. Based on the actual production process of titanium alloy powder metallurgy products, the detection of defects by optical microscopy, scanning electron microscopy (SEM) and non-destructive testing technology is discussed. The formation process and mechanism of these defects are analyzed in detail, aiming at providing new strategies to solve the quality problems of products. It provides theoretical basis and engineering practice suggestions for improving the processing quality of titanium alloy powder metallurgy products. Through targeted defect improvement methods, the performance of titanium alloy powder metallurgy products can be significantly enhanced to better meet the requirements of various applications.
