Liquid-Solid Microextrusion of Aluminum Alloy
AI summary Read the abstract
This study develops a liquid-solid microextrusion process for forming aluminum alloy microshafts of 1 mm diameter, investigating the effects of forming temperature on microstructure and mechanical properties.
Liquid-solid microextrusion is one type of microplastic forming processes at elevated temperature and can be used in the forming of pins, screws, shafts, and gears in micro-scale. Microextrusion setup operated by use of ball screw was designed and fabricated by authors. Microshaft of diameter 1 mm was extruded in the liquid-solid state at different forming temperature from Al-Mg alloy ER5356 billet of 4 mm in diameter. Heating temperature in the furnace for billet were set 650, 700, 750, and 800 degree C which was corresponding to the forming temperature range from 475 to 631 degree C because of temperature drop during transfer from furnace to mold. Forming load ranged from 4kN to 8kN. Microstructural observation shows that the grain size was reduced greatly compared to the original billet material. Microindention hardness shows that the extruded pin was strengthened which caused by small grain size.

Al2O3 produced by the sol-gel method for microcomposite ceramics
AI summary Read the abstract
Sol-gel derived alumina was shown to produce microcomposite ceramic structures with microplastic properties at room temperature, achieving high strength through localized flow at structural defect sites. Understanding how microplastic flow in composite ceramics can be engineered through processing parallels ongoing research into modifying polymer composite structures to reduce microplastic generation.
Measurement of Microdeformation for Aluminum Specimen with Large Grain
AI summary Read the abstract
Laser-based optical measurement was used to analyze the non-uniform microdeformation of aluminum specimens with large grains, revealing high shear strains at grain boundaries during slip. The experimental results provide direct evidence supporting theories of microplastic deformation at grain boundaries in coarse-grained metals.
Numerical study of microplastic impact hydroforming process
AI summary Read the abstract
This manufacturing engineering paper (with 'microplastic' in the title referring to small-scale plastic deformation of metals) presents finite element simulations of an impact hydroforming process for making tiny metal components. Note: this paper uses 'microplastic forming' in a materials science context, not environmental microplastics.
