Heat-Input-Dependent CGHAZ Microstructural Evolution and Impact Toughness of Two X65 Seamless Pipeline Steels with Different Composition–Microstructure Characteristics

Tianxiang Jiao, Junye Li, Xuelin Wang, Ping Hu et autres

This study comparatively investigates the coarse-grained heat-affected zone (CGHAZ) responses of two industrial X65 seamless pipeline steels with distinct composition–microstructure characteristics under simulated girth-welding thermal cycles. One steel exhibits a predominantly bainitic initial microstructure, whereas the other consists of a ferrite–bainite dual-phase …

OBP-HRNetV2: An attention-enhanced network for robust safflower filament picking point localization in field environments

Zhenguo Zhang, Junye Li, Ruimeng Shi, Yunze Wang et autres

The core prerequisite for an intelligent safflower harvesting robot is accurate picking-point localization. Owing to the filament's diminutive dimensions and the indistinct boundary contours at the intended picking loci, the harvesting mechanism is precluded from attaining sub-pixel localization accuracy. This study instantiates …

Effect of acicular ferrite on microstructure stability and low-temperature impact toughness of simulated CGHAZ in X65 grade submarine pipeline steel

Xuelin Wang, Siwei Lin, Tianxiang Jiao, Junye Li et autres

Two X65 submarine pipeline steels with distinct microstructures, namely quasi-polygonal ferrite (QPF)-bainite dual-phase steel and acicular ferrite (AF)-dominant steel, were used to investigate the effects of microstructure on the microstructural stability and low-temperature impact toughness of simulated coarse-grained heat-affected zones (CGHAZs) after …

Optimisation of Key Parameters of Oil Injection Lubrication and Analysis of Lubrication Efficiency of Textured Gears

Zi'ang Zhang, Junye Li, Tiangang Zou, Wei Hou et autres

ABSTRACT To improve gear lubrication efficiency, this paper designs a new arc groove gear structure and proposes an optimised nozzle arrangement based on it. Firstly, the effect of nozzle arrangement on tooth surface temperature is studied through simulation analysis. The results show …
