High-strength and highly-uniform composites produced by compocasting and cold rolling processes

Fabrication of A356 composite reinforced with micro and nano Al2O3 particles by a developed compocasting method and study of its properties

“…In both the processes, the vortex is used and the composites have high porosity. To decrease the porosity density in the composite material, the pressure casting such as die and squeeze casting methods are needed [12][13][14]. Squeeze casting has greater potential to create less defective cast components [15].…”

“…Although compocasting is generally accepted as a commercial route for the production of MMCs [13,14,25], there are technical challenges associated with producing a homogeneous, high density composite. The challenges rise up specially, with increasing alumina weight fraction and decreasing size of the particles, because of the poor wetting between matrix alloys and some reinforcements [26].…”

Gradual formation of nano/ultrafine structure under accumulative press bonding (APB) process

“…11 processes of ultra-fine grain subdivision, where recovery to form clear sub-boundaries and shortrange grain boundary migration can be observed [50][51][52][53].…”

Surface Performance Multiobjective Decision of a Cold Roll-Beating Spline with the Entropy Weight Ideal Point Method

“…The technology has high production efficiency and low cost and requires no cutting or chip production. In the automotive industry, aerospace industry, major strategic equipment industry, and other fields that utilize a spline, gear and screw processing has been widely used [4,5]. In the cold roll-beating forming process, the spline surface performance directly affects the use performance of the spline.…”
