Diagnostic performance of strain ratio combined with conventional ultrasound for cervical lymph node metastasis in head and neck neoplasms
Abstract Cervical lymph node metastasis is a key prognostic factor in head and neck neoplasms, yet conventional ultrasound alone is limited by morphological overlap between metastatic and benign nodes. This study aimed to evaluate the diagnostic performance of a combined model integrating the ultrasound strain elastography (USE)-derived strain ratio (SR) with conventional ultrasound parameters and to assess its superiority over individual parameters alone.
Microstructure and Properties Evolution of 7075 Al alloy in Hot Rolling and Short Process Heat Treatment
7075 aluminum alloy is widely used in the aerospace field because of its low density, high specific strength, high fracture toughness, and good machinability. This paper systematically studied the evolution of the microstructure and properties of 7075 aluminum alloy at different temperatures. Based on the rolling and heat treatment process, a short process of rolling and heat treatment is proposed, which can significantly improve the properties.
Effect of hot deformation on microstructure and porosity of additively manufactured 7050 Al alloy
Wire arc additive manufacturing technology of 7050 aluminum alloy has a broad application prospect in aerospace field. But the lack of comprehensive properties caused by coarse columnar grains and pores has become an important bottleneck. In this study, hot compression was conducted to simulate forging process to investigate the microstructure improvement of as-deposited 7050 Al alloy by plastic deformation.
